Sleep phases in infants by month - possible cycles

From birth, the child’s body begins careful work to adapt to the world around it. Sleep is especially important in this process, since during rest the information received is processed, the immune system is strengthened, and the nervous system develops. Unlike an adult, a baby's sleep has its own characteristics. Therefore, when drawing up a baby’s night and daytime rest regime, you need to take into account all the necessary requirements.

A baby's sleep is important for its development and adaptation to the world around it.

From a month to three

A one-month-old baby manages to adapt to the environment and begins to show interest in the world.
His digestive system has already adapted to digesting food, and his body has adapted to lower temperatures. While awake, he does not feel such discomfort as in the first days of life, so he begins to show activity, which it is advisable to encourage in every possible way. A newborn usually wakes up from a feeling of hunger and immediately begins to cry, and a month-old baby can lie quietly and examine surrounding objects for some time after waking up. If at this time his mother comes up and begins to communicate with him, he will respond with pleasure to her appeal. This is how a regime of alternating sleep and wakefulness begins to form, which will be observed for up to 1.5-2 years. At this age, a baby should sleep a total of 16-18 hours. Night sleep accounts for approximately 10-11 hours of this, but it is not continuous. Depending on when you put your baby to bed, he will wake up briefly 1 or 2 times to eat.

When going to bed at 20-21 o'clock, the child eats twice, when later, one feeding per night is enough.

During the day, a baby up to 3 months should sleep another 5-6 hours. His body itself distributes them more or less evenly throughout the day. Even if you do not impose a certain regime on the child, you will notice that at 11-12, and then at about 15-16 hours the baby shows signs of drowsiness: he begins to yawn, be capricious, and rub his eyes. This triggers the biological clock, indicating that the child needs rest. The timing of the third nap depends on when your baby wakes up in the morning.

Active wakefulness during the day occurs mainly before feeding. The mother should use this period to develop the baby and communicate with him. A two-month-old baby can already:

• recognize your relatives and smile at them;
• hold your head well;
• turn the head towards the sound source;
• respond to an appeal to him;
• actively move your arms and legs.

After sleep, it is advisable to pick him up, carry him around the room in an upright position, chat, do a light massage or gymnastics. Children react very positively to such manipulations. Having eaten, the baby quickly falls asleep, since the feeding process itself is a serious physical activity for him.

Formation of the regime

Since the body responds well to training, the formation of a daily routine is very important.

To do this, you must try to maintain constant intervals of basic activities: feeding, sleeping, bathing and communication.

Depending on the character of your child, the daily routine can be either strict (for capricious children) or allow small liberties (suitable for obedient children). A young mother should clearly understand this point.

It is important not to break the regime, even if you go on a trip or visit. The regime comes first, and all other life events come second. This will help the child always feel at ease, feel protected, because his usual rhythm will not be disrupted.

Sleep phases

Recording bioelectrical oscillations in the process of studying physiological processes made it possible to find out that sleep is a cyclical process in which phases replace each other.

Sensors attached to the head of a sleeping person during an electroencephalogram record slow vibrations. Gradually they are replaced by fast ones. Soon they return to slow again. Such data allowed us to talk about the presence of two phases: fast and slow.

Paradoxical phase

The rapid phase is also called paradoxical sleep or REM from the English “active eye movement”. Distinctive features of sleep at this stage are:

• active eye movement;
• trembling of eyelashes;
• increased breathing;
• increased heart rate;
• complete immobility of the body.

Body temperature and blood pressure may increase.

The paradoxical phase of sleep for newborns is very important. At this time, brain development is stimulated, nervous and psycho-emotional tension is relieved, new information is processed, the endocrine system is rebooted and emotional. At this stage, the baby sees dreams that train and develop the brain. Dreams are so vivid that even if a child could wake up and tell them, he would not be able to distinguish them from reality.

As children develop, the proportion of the paradoxical stage decreases.

Orthodox phase

The slow phase is called orthodox or non-REM. This stage is named because of the slow rotation of the eyeballs. During the orthodox stage, all body functions slow down.

In a baby, slow-wave sleep includes 2 stages. At 4 months or later, 4 stages appear. If in a newborn the slow phase occupies 25-30%, then by the year it is already 60-65%. This is due to the immaturity of the cerebral cortex at birth and the gradual maturation process in the first year of a child's life. The proportion of the slow phase increases, because at this stage of sleep energy is restored. A growing body spends a lot of energy and requires more rest.

Stages of the Orthodox phase:

1. Nap (alpha sleep). The baby falls asleep, but continues to respond to many sounds. The muscles relax completely, and limbs may twitch.
2. Falling asleep (light rest) is the process of transition from drowsiness to a state of rest. The child wakes up to extraneous sounds.
3. During deep sleep, the body relaxes and the limbs become heavy.
4. During the very deep sleep stage, children become completely relaxed. They are difficult to wake up, and if they do, they become disoriented. The first time after waking up will be accompanied by crying and whimpering.

Phase rotation

As children grow, the structure of their sleep also changes. In adults, the slow phase comes first, followed by the fast phase. In a newborn, the REM sleep phase becomes orthodox. This is due to the fact that the parts of the brain that are responsible for the fast phase develop earlier. At 2-3 months, the infant’s sleep phase pattern becomes similar to that of an adult.

The ratio of phase durations also changes. In one-month-old babies, REM sleep accounts for 70-75% of the entire rest period. In an infant at 6 months, this stage decreases to 35-40%. The relationship between the paradoxical and orthodox sleep phases of infants is more clearly presented in the table by month:

The newborn usually wakes up every time the cycle ends. The older he gets, the more cycles are included in rest, especially at night. Awakening at the end of the cycle no longer occurs. A baby's sleep cycle is approximately:

You can easily see the transition from one cycle to another in a baby: without waking up, he shudders, whines, cries.

Parents often notice the baby's restless rest when he wakes up from the slightest rustle. Or a deep sleep, from which it is difficult to wake up the baby at the moment when you need to go to the clinic or store. These phenomena in themselves worry mom and dad. However, if you know the characteristics of sleep phases in children, it is easy to understand that periods of superficial rest and deep rest are normal physiological phenomena.

Features of the baby cycle

Starting from 3-5 months, a child sleeps almost the same as an adult, with the exception of the duration of sleep cycles. A full cycle consists of 4 stages of a slow phase and a fast phase.

At a very early age, one cycle lasts approximately 40-50 minutes; starting from 5-10 years, it reaches 60-70 minutes, and only from 10-12 years does it become the same as in adults. The peculiarity of babies' sleep is that their slow-wave sleep phase is quite short and only begins to increase as they grow older.

As in adults, in children the duration of deep sleep decreases with each new phase. Closer to the morning, it may not exist at all, only superficial sleep with vivid dreams.

It is worth noting that daytime rest at different times has its own characteristics. Let's look at them in more detail.

• First nap of the day (morning). This is a kind of continuation of night sleep, which was interrupted for feeding and hygiene procedures. At this time, babies see vivid dreams, characteristic of the fast phase; they can twitch their arms and legs in their sleep, smile, and change their facial expressions.
• Second nap (lunch). At this time, the baby already has time to spend his energy on performing certain tasks, so he needs to restore it. Lunchtime sleep is mostly slow, during which growth hormone is actively produced in the body.
• Third nap (evening). The last rest of the day is necessary for the baby to reach the night's sleep without overtiring the body. This sleep is quite light; during it, the baby also dreams and reacts to external stimuli.

Sleep standards for children under one year old

With each new month, changes occur in the baby's life. It grows and develops rapidly. The periods between feedings increase, the diet expands, and the amount of sleep during the day decreases.

1. In the first two months, the baby sleeps at least 18-20 hours. Of these, 12 hours are in the dark. Night sleep is usually interrupted by two feedings. During the day, babies sleep 4-5 times. Each period lasts about 2 hours. During these months, the baby wakes up briefly to feed and soon falls asleep again.
2. At three to four months, periods of wakefulness increase. A child can play for up to 2 hours during the day before he begins to need rest. Night feeding is reduced to 1 time, sleep duration is 11 hours.
3. From five months to six months there are no fundamental changes. The duration of the night's rest does not change, but many babies can already do without feeding. During the day the baby sleeps 3 times for 2 hours. He plays with pleasure for 2-3 hours and only then begins to act up and rub his eyes.
4. From seven to nine months, the child’s motor activity increases. He explores the world with interest. If it is noticeable that his nervous system is not overtired, daytime sleep can be reduced to 2 times. At night, the baby should rest for 10 hours. Most children at this age categorically refuse to eat at night.
5. From ten months to one year, the child’s body needs 2 naps during the day. The duration of each period is approximately 2.5 hours. Night rest remains unchanged - 10 hours.

In conclusion

Infants sleep differently than adults. Their sleep phases have different order and duration. This is directly related to the incomplete development of all organs and systems, in particular the brain. The areas responsible for REM sleep function normally even while the baby is in the womb. But the areas that control the slow phase begin their active activity only at 2-5 months.

As the baby grows older, he needs rest less and less, but his sleep in any case should be calm and complete.

Why sleep is so important for babies

From the moment of birth and during the first years of life, the child sleeps most of the day. Over time, the total amount of rest is reduced to 10-11 hours, but this figure still exceeds the norm for an adult. Some children by the age of 4-5 completely abandon daytime sleep in favor of nighttime sleep, while others continue to adhere to lunchtime naps even in elementary school. Knowledge about the peculiarities of daytime and nighttime rest will help to understand why this happens.

Night rest

From the first days of life, every newborn has no concept of day and night - the moments of falling asleep and waking up correspond to the physiological needs of the body. Since the digestion of mother's milk only takes about 75 minutes, and then hunger sets in again, babies sleep not long, but often. It is not possible to track cyclicity at this age, but it is known that about 70% of rest is occupied by the fast-wave phase. Thanks to this, the brain develops quickly.

In the process of growing up, the speed of perception of information about the world around us decreases, and physical activity increases. For this reason, rest is gradually divided into alternating phases. The fast-wave period becomes shorter, and the slow-wave period lengthens. Sleep cycles also appear. Between periods, the baby wakes up to eat or go to the toilet, and then falls asleep again.

By three months, the cycle can already be divided into intervals that are characterized by certain forms of behavior:

• After falling asleep, deep sleep immediately sets in;
• During the fast-wave period, the baby shows increased activity;
• Between cycles, sleep is interrupted;
• By increasing the time of the slow-wave phase, the total duration of rest is reduced;
• The child begins to see the difference between day and night - in the absence of light, falling asleep again occurs quickly, and at lunchtime, after sleep, awakening occurs.

Day rest

It has the same importance for a child as the night one - a long fast-wave period allows you to assimilate information received in the morning and relieve the nervous system.
It is precisely because of the overabundance of new data that the baby becomes capricious, freaks out, and throws tantrums. In this state, the best solution is to put him to bed as soon as possible. Depending on age, the ratio of daytime and nighttime rest varies. This is due to the characteristics of sleep during daylight hours.

Morning

Additional naps in the morning are necessary when the night's rest has been interrupted by feeding or hygiene procedures. Usually the breaks end at the age of six months. During these hours, the deep phase does not occur, since the baby is not yet physically tired. The fast-wave period can be easily interrupted by loud sounds, so doctors recommend parents to be quieter.

Dinner

By lunchtime, the child has already shown enough physical activity, spent accumulated energy, reinforced his mind with new impressions, so he needs a rest of normal duration. During the daytime, a slow phase is necessarily present, as physical recovery is necessary.

Evening

Evening additional sleep is similar to morning sleep - it is necessary for the restoration of the nervous system, so it proceeds superficially.

Features of sleep in young children

Basic knowledge about the functioning of various body systems during periods of activity and rest can help improve the quality of life for young parents and their babies. So, let’s take a closer look at the stages of sleep formation in a child.

Fetal sleep before birth: research results

According to research results, the fetus in the womb of a pregnant woman spends the vast majority of time in the power of Morpheus. Interesting to know! There is an opinion that in later stages an unborn child can even dream.

Many expectant mothers are concerned about the daytime calm and nighttime activity of the baby. In fact, the reason for this “abnormal behavior” is obvious: during the day, when walking, the mother’s movements rock and lull her to sleep. At night, after a long daytime “time out,” the baby wakes up and begins to move actively.

Rest for a newborn: day and night, norms

The periods of sleep of an infant in their rhythms differ little from the intrauterine regime.
A newborn does not have the traditional concept of day and night. During this period, peace is unstable, the child wakes up very often and cries demandingly. In this way, the baby calls adults, “informs” them about various problems that interfere with proper rest: thirst, hunger, uncomfortable air temperature. For this reason, young children are also called “callers” or “signalers.” It is important to know! Thanks to infant sleep, the process of thinking development occurs. In addition, growth hormone is synthesized during night rest.

It is not surprising that babies sleep almost 24 hours a day.

Building healthy habits can start from the earliest days. This is quite possible for young parents

It is important to methodically follow the sequence of actions. Getting up is hygienic procedures: washing, massage, cleaning the nose, ears

The child will subsequently associate such rituals with morning time. Walks are carried out during the day, but the retreat to night rest is indicated by evening bathing, feeding, and lulling. The main thing in this matter is a constant regime, because children are well-known conservatives and traditionalists, for whom stability in daily actions is a vital necessity.

Changes in children's sleep patterns after a month of life

There are generally accepted norms for daytime and nighttime sleep in infants by month, which are presented in the following table:

REM sleep

The fast or paradoxical phase is the most important in the life of a newborn. It is also called REM (rapid eye movement). The name speaks for itself; at this stage, children's eyelashes often flutter, and eye movement is visible under closed eyelids. These signs often mislead young parents, as they may think that the baby is not asleep.

Meanwhile, very important processes occur in this phase:

• intensive brain development due to vivid dreams;
• relieving stress and tension;
• consolidation of new information and reflection on it;
• rebooting the brain.

Baby is sleeping

The child enters the paradoxical phase immediately from the waking state. The brain is very active at this time and seems to be on the verge of the world of dreams and reality. Over time, the proportion of this phase becomes smaller.

In the paradoxical phase, newborns already dream and also react to them by smiling, wincing, frowning and twitching their arms and legs.

What they see in their dreams is not known for certain, but there is a theory that at first children see spots of light, the image of their mother’s breast, and also experience sensations that they have already become familiar with in the real world.

As the baby explores the new world and develops, he will begin to see more and more information in dreams: the faces of his parents, his room, familiar objects, and also distinguish a wide range of sensations.

How to help your baby sleep through the night

One way to help your child learn to fall asleep on his own at night is to ensure that when he wakes up, he is surrounded by the same things that were around him when he fell asleep. If he fell asleep in his mother’s arms with the TV on, this is what he associates his sleep with and would like it to be like this in the middle of the night when he wakes up!

You can teach your child to fall asleep on his own within a week, but at the very beginning he will need a lot of support from you.

It's important to first establish an effective, consistent bedtime routine. As soon as this ritual comes to an end, put your baby in his crib, kiss him and leave the room.

Come back in a few seconds, then a few minutes later for another kiss and goodnight. Children who can get out of their crib on their own can follow you. Don't worry, just turn around and act surprised that the baby is not in the crib. He'll laugh and love the game of being in his crib, head on the pillow, before you come to kiss him goodnight.

It is very important that your child trusts you and is not afraid. There's no need to leave him crying

Experts do not recommend this technique, although it can be effective. It is based on the powerful and unpredictable emotion of fear and causes stress in both the child and the parent.

How much sleep should a seven week old baby normally sleep?

Sleep patterns in seven-week-old babies, day and night

At 7 months the child begins to express himself energetically.

Parents should accustom him to active games in the first half of the day, and to quiet activities in the afternoon. Then the baby will sleep well.

A child of this age needs 18 hours of sleep per day. If your child sleeps longer, he may feel unwell.

The baby should not be weaned from the sleep-wake schedule.

How much and how should a baby sleep at 7 weeks?

A 7-week-old baby's naps are no different from those of a 6-week-old baby.

Rest is divided into 4 periods: 2 for 3 hours and 2 for 30-40 minutes.

It is advisable that the first periods of deep sleep take place in the first half of the day, and the second shallow periods in the evening.

In just one day, a baby can sleep up to 8 hours. And he needs 10 hours to rest at night.

Why does a baby sleep poorly at night and during the day at seven weeks of life: reasons

We wrote above about active games; they should take place during the day.

Another reason for poor sleep is an uncomfortable pillow or mattress. Since the baby is already beginning to move, he can, of course, slide down during sleep and lie down as he wants.

In this problem, swaddling saves parents. Wrapped in a warm blanket, the child will not want to crawl or move anywhere.

By the way, swaddling also prevents the baby from flinching.

Tips for parents to restore sleep patterns

According to experts, before choosing ways to prolong a baby’s sleep phases if the sleep schedule has gone wrong, it is necessary to understand the reasons for such a disorder.

Healthy baby sleep depends on proper sleeping conditions

The most common factors that interfere with a child’s sleep patterns and subsequent proper rest are identified:

• Violation of the “quiet hour” cycle leads to overwork and negatively affects evening bedtime and falling asleep at night;
• Inattention to the needs of the baby, for example, he may wake up from discomfort resulting from improperly selected clothing, thirst or hunger;
• Infants do not sleep well at night if the air humidity in the room is high and the thermal regime is disrupted;
• Intestinal colic can interfere with falling asleep.

Even at the age of several weeks, the baby is able to understand the difference between day and night if he is positioned correctly. Then your sleep pattern will not be disrupted. For this, experts recommend:

• Before going to bed at night, observe a useful ritual, each family has its own;
• It is better to combine bedtime at night with the family’s routine. If household members go to bed late, you need to calculate the hours so that first the baby sleeps until the first night feeding, and then falls asleep with the whole family;
• It is useful to take a bath in warm water before going to bed at night. However, you need to make sure that the child does not get too excited when playing with water. It is better to take a bath early before falling asleep so that he calms down, eats well and sleeps soundly;
• Mother's lullaby or soothing music helps to fall asleep;
• Experienced mothers say that a child falls asleep better next to a musical toy that plays a melody quietly and glows dimly for several minutes.

For your information! Pediatric somnologists offer the following effective measures to help improve a baby's sleep: a light soothing massage, dense feeding, clean natural linen, a comfortable crib.

The amount of sleep a child gets is constantly changing as he/she gets older.

When drawing up a regimen for children of the first year, it is necessary to take into account that the duration of sleep cycles is constantly changing, for example, in newborns - every 2 weeks. In addition, babies develop individually, which affects their personal sleep pattern. If the mother cannot properly organize the cycles of night and day rest, recommendations from specialists will come to the rescue.

Table of sleep norms for a child with explanations

• Some children over 3 years old can do without daytime sleep, but then at night sleep should fully correspond to the total daily requirement for children of this age.
• This table should not be treated as a standard. Each child is individual, and if yours sleeps one or two hours less or more, but at the same time his mood is favorable, he is not whiny and develops adequately, then you should not specifically change his daily routine.

Sleep standards for a baby from 1 to 3 months

• If the baby sleeps constantly for the first month, with only short periods of wakefulness, then at the age of 2-3 months the child already examines and somehow perceives the world around him.
• But the baby should not go without sleep for longer than 2 hours. His nervous system is still weak and overwork easily occurs. Monitor your child's behavior. If he becomes lethargic, rubs his eyes and yawns, stop all games and go to bed.

Sleep standards for a child from 3 to 6 months

During this period, the baby should sleep 14-17 hours. Moreover, 10-12 hours at night, and the rest of the time is divided between 3-4 daytime sleeps. By the age of six months, he can already sleep the whole night without interruption, but only if you teach him to sleep healthy. To do this, do not rock your baby to sleep, do not put him to sleep next to you, and do not teach your child to fall asleep while feeding.

Sleep standards for a child from 6 months to a year

In the second half of the year, the baby should sleep at least 10-12 hours at night and another 2-3 hours during the day. Daytime sleep is divided into two or three doses, depending on the child's temperament and the established daily routine.

Now the baby may begin to have certain problems with sleep. The reason is that at this time the child learns to crawl and walk, so even in his sleep he can “practice.” If the baby gets up in bed in the middle of the night, he will not be able to lie back down. You will have to come, calm the child and put him back down.

Sleep standards for a child from 1 to 2 years old

A one-year-old child can already sleep through the night. But during 10-12 hours of sleep, you will probably have to lift him to the potty once or twice. Up to 18 months, the baby can maintain 2 naps during the day. Then one is enough for him.

Now it is very important for you to monitor the safety of your baby. Lower the mattress in the crib down, because the child may try to climb over the side in the middle of the night

You can also lay blankets or soft toys by the bed if your baby is a real fidget.

Sleep standards for a child from 2 to 4 years old

The daily need for sleep in children 2-4 years old is 11-13 hours. Moreover, starting from the age of three, the baby will be able to do without daytime sleep. At the same time, he can be transferred to a new large bed. Then the child will be able to get up on his own at night to go to the toilet and get up freely early in the morning, when everyone else is still sleeping.

Sleep standards for a child from 4 to 7 years old

• A child between 4 and 7 years old needs to sleep about 12 hours a day. Those children who go to kindergarten can sleep during the day until they are 6-7 years old. Daytime sleep at this time lasts 1.5 – 2 hours.
• The baby’s nervous system has already strengthened to such an extent that he can easily withstand 12 hours of active wakefulness.
• At this age, the child can already go to bed on his own and fall asleep without parental help. Of course, it is still advisable for four-year-olds to read fairy tales before bed, but seven-year-olds should already fall asleep on their own.

Does your child wake up too early?

Most children between the ages of one and three like to come to their parents' room after they wake up for cuddles. But your child’s “morning” may be different from yours, because he goes to bed much earlier than you, and by 5.30 am he may already be well asleep. Waking up early is a common cause of parental sleep deprivation because it wakes parents before their dreaming phase is over.

It may be impossible to keep a wide-awake child in bed early in the morning. However, it is quite possible to teach your baby to stay in bed for a while longer. The trick is to tell your child when morning begins. Although dawn may be a very obvious visual cue, its timing may not always suit parents' practical goals.

The best visual cue can be a clock, but children between the ages of one and three years old do not yet know how to tell time by clocks. You can buy special watches with lugs that rise at a set time. But what time should I set? Of course, you don’t want to wake up your child if he suddenly decides to sleep longer in the morning.

An easier solution would be to install a radio alarm clock in another room. When your baby wakes up early, go to him and whisper in his ear that it is still night and everything is quiet. And when the radio turns on, return to his room, draw his attention to the music playing, loudly wish him good morning. Open the curtains or turn on the lights and begin your morning routine.

First, set the radio alarm time very early, on the second day you can delay it by a few minutes, on the third day set the time later, and so on. This way, you will gradually shift your child's wake-up time until it becomes acceptable to you. The child will soon understand that it is time to wake up when he hears music.

Sleep patterns as you get older

Let's look at how a baby's sleep progresses by month.

1. During the first month of life, the little one sleeps almost all day. He rests up to 22 hours a day. The stress suffered during childbirth and the new environment require adaptation from the baby. He manages to do this best in his sleep. Periods of wakefulness at this age are very short, about 40 minutes.
2. In the second month of life, a baby may no longer sleep for an entire hour, sometimes even 1.5 hours. He spends a total of 15 to 18 hours sleeping. At this stage of their development, babies experience something like a kind of “crisis”, manifested by difficulty falling asleep and frequent awakenings for no reason. This should not be a cause for concern for parents. What is happening to the child is normal. During daylight hours, the baby wakes up about five times every 40-120 minutes. In the dark, the baby can rest continuously, without waking up, for 5 hours.
3. Babies in the third month of life tend to sleep less during daylight hours. Daytime rest now takes approximately 5.5 hours, and nighttime – about 11. During light hours, sleep lasts from 40 minutes to 120 minutes. At this age, it is time for parents to accustom the baby to the fact that in the evening he should fall asleep from 19.00 to 22.00, while observing the appearance of the first signs of fatigue in the baby. As soon as they are noticed, immediately put the baby in the crib.
4. In the fourth month of life, the body begins to produce melatonin (sleep hormone), which contributes to the normal development of the baby. Since this hormone is better produced in the dark, care must be taken to ensure that the baby’s night’s sleep is as sound and quality as possible, and lasts at least 11 hours (in total). He only breaks to feed once during the night.
5. In five-month-old babies, there is a reduction in the total daily sleep time to 14-17 hours. During daylight hours, the baby sleeps three times for 2 hours. A night's rest takes him about 12 hours. During this period of the baby’s life, parents should start adjusting the daily schedule taking into account the characteristics of his behavior.
6. Six-month-old babies sleep no more than 3-4 hours in the daytime, and about 12 in the dark. Periods of continuous wakefulness in babies of this age already reach 2-2.5 hours. During the day, babies are put to rest twice for 1.5 hours.
7. In the seventh month, children establish a stable two-hour daytime rest, while the nighttime rest takes from 10 to 12 hours. The duration of the waking phase reaches 3 hours.
8. An eight-month-old baby is in a state of sleep during the day for a total of about 15 hours, of which 3 hours are allocated to two hour and a half day rest. Waking periods now last up to 3.5 hours. The child spends this time cheerfully and is active. During the night he may no longer wake up.
9. In the ninth to tenth month of life, babies sleep 14-15 hours a day. Children refuse evening sleep, as it leads to a deterioration in the baby’s mood and harms night’s rest. The baby is already able to fall asleep on his own, even when he wakes up at night. Parents clearly notice the presence of individual characteristics of their child’s sleep patterns.
10. A special feature of children aged eleven to twelve months is their ability to adapt to an individual schedule. Mom and dad can already try to accustom the baby to evenly distributed daytime sleep.

Thanks to this measure, night sleep becomes stronger. One-year-old babies get used to one day's rest. In total, they sleep about 12-14 hours during the day. The intervals of continuous wakefulness are now 6 hours.
