Infant sleep

In the life of infants and toddlers, sleep takes up most of the time. Therefore, parents are very concerned about the baby’s sleep. Adequate sleep is very important for the physical and intellectual development of infants and young children. Because adequate sleep can promote the development and development of brain function, which is conducive to the storage of brain energy, memory consolidation and physical recovery. Insufficient sleep can affect the development of children’s cognitive function, damage the function of the frontal cortex of the brain, leading to changes in emotion and attention, leading to defects in language and abstract thinking functions.

In terms of total sleep time, the smaller the child, the more sleep. Newborns up to 2 months of babies sleep 14-18 hours a day, 2-4 months of babies sleep an average of 14-15 hours a day, 4-6 months of average baby sleep time 13-14 hours a day. However, there are individual differences in sleep time. Not every child is the same. Some babies have less sleep time, but when they are awake, their mental state is very good and their diet is not affected. Don’t worry. infant sleep

The newborn’s sleep is not up-and-night, often upside down, but as the nervous system matures, it will slowly produce a relatively stable sleep and wake up. And with age, sleep time during the day is shortened, and wake time is prolonged. Newborns wake up 1-2 hours every 3-4 hours, and wake up 3-4 hours at 4 months. After 3 months, the sleep time is slowly reduced during the day, with a fixed nap time and a long night at night. About 44% of the babies started to sleep at night for 2 months. The 6-month-old baby has a maximum sleep period of 6 hours at night, and the average sleep time from 6 months to 5 years old is about 11 hours. Some parents worry that their baby will be hungry at night, but don’t worry about it. According to the study, a 4-month-old healthy full-term child can sleep for 6 hours without eating, 5 months can sleep for 9 hours without eating, and 6 months can sleep for 12 hours without eating. And the baby does not eat at night, eat more during the day, so parents do not have to worry about the baby’s undernutrition. But don’t let the newborn sleep for more than 4 hours at night. If the newborn sleeps for more than 3 hours during the day, he should wake him up and feed him.

Infant Sleep

Sleep sleep (eye movement sleep), and deep sleep (non-eye movement sleep). In infants and young children, when you are sleeping, your baby may have all kinds of strange movements, sometimes sucking, sometimes smiling, sometimes like making faces, sometimes grinning, sometimes with large dance-like limb movements. The body is stretched, sometimes suddenly trembles, occasionally vocalizes, the breathing is irregular, and the eye moves under the closed or semi-closed eyelids. Infants sleeping for the first 2 years after birth account for most of the sleep time. Shallow sleep plays an important physiological and psychological role in the development of infants and young children. Studies have shown that shallow sleep can increase the synthesis and metabolism of proteins in the human body, so that the new knowledge learned can be retained. Therefore, parents should not worry because the baby makes some strange movements during light sleep, and do not make the behavior of waking up the baby or picking up the baby to interrupt the baby’s shallow sleep.

In the neonatal period, sleep begins with shallow sleep, and after about 15 minutes, it enters deep sleep, then enters shallow sleep, and finally wakes up. Half sleep and half sleep in each sleep cycle. Sleep behavior and physiological function gradually matured 2-3 months after birth. The pattern of sleep gradually changed from deep sleep in 3 months (from adult sleep to deep sleep), and the deep sleep time was extended, and the deep sleep time was 2 times that of shallow sleep. By 6 months, 82% of babies sleep from deep sleep. 2-5 years old, the light sleep time gradually decreased from 30% to 20%-25% (equivalent to adult level). Moreover, physical activity is also less when sleeping lightly, and shallow sleep is more obvious in the latter half of the night, and it develops into adulthood.

The sleep cycle also increases with age, with an average of 45 minutes per sleep cycle for a newborn and 60 minutes for a sleep cycle of 2-3 years.

Newborns up to 2 months of babies, each sleep lasts no more than 4 hours. Because the baby’s nerves are not mature enough to allow him to relax and fall asleep. Parents can help the baby to fall asleep by wrapping, gently shaking, feeding, and using a pacifier. Don’t worry about spoiling the child or developing a permanent bad habit, because the baby within 3 months does not remember the surrounding environment. But starting from 4-6 months, we should develop good sleep habits for your baby, Infant sleep

If your baby sleeps late, you can wake up the baby in advance in the morning and gradually advance the time to fall asleep. Take a nap during the day, sleep too much during the day or get too tired during the day, or feel too close to the night during the day and sleep well at night. Don’t be too excited to play 1-2 hours before going to bed, you can do some quiet activities, such as reading books, telling stories, etc. Take a warm bath before going to bed, do baby touch, it is also good for your baby to fall asleep. Don’t eat too much before going to bed, and you can’t be hungry. Don’t let your baby eat a teat or a pacifier to fall asleep, avoiding the bad habit of holding, patting, and shaking before going to bed. Because if you use the above method when you fall asleep, you will still need to use the above-mentioned sleeping behavior to fall asleep when the baby wakes up in the middle of the night. The specific method of cultivating your baby’s good sleep habits may not be the same for each baby, but the basic principle is to give as much comfort as possible and spend more time letting the baby learn to fall asleep.
