Newborns need to sleep for an average of 16 hours a day (the range is 14-20 hours), and each sleep cycle is about 45 minutes. In a sleep cycle, light sleep and deep sleep account for about half of the time. Newborns sleep most of the time. From one sleep cycle to another, wake up every 2-4 hours to eat milk and open your eyes for a few minutes to 1 hour. The circadian rhythm has not yet been determined.
1-3-month-old infants' average sleep time is about 15 hours per day. At the age of 2 months, 44% of babies can sleep for 5-6 hours at night. Awakening time is prolonged during the day.
The average sleep time of a 6-month-old baby is about 14 hours a day. During this period, most babies can sleep for a long time at night and sleep for 6 hours.
1 year-old, she sleeps 13- 14 hours a day on average, and sleeps until dawn. She stays awake for a long time during the day and has a fixed nap time of 2-3 times.
With the increase of age, children's sleep time will be reduced, and regular work and rest time will be gradually established. 1 Children aged 2 should get 13 to 14 hours of sleep every day, and children aged 2 to 4 should get 1 1 hour of sleep every day. Children should also ensure 8- 10 hours of sleep.
The sleep time of different babies varies greatly. If your baby can't sleep that much, but he wakes up in good spirits, don't worry about his lack of sleep, because he will sleep naturally when he is sleepy.
How to judge whether sleep is enough?
Some babies will "hum" at night, or suddenly shake their hands and feet, or kick the quilt to eat their hands, indicating that the baby is in a shallow sleep state and does not affect his health. On the contrary, it is as important to the development of the body and brain as deep sleep. "At this time, parents should not be too nervous. Look around. If it is a light sleep, let the baby fall asleep naturally and ensure that he can get a lasting sleep. "
Children can automatically fall asleep on time, fall asleep quickly, enter deep sleep in about 30 minutes, sleep comfortably and sleep deeply. Can wake up on time, do not stay in bed, do not cry. Wake up full of energy, no fatigue, good appetite and happy mood.
The baby's sleeping position should not be "fixed"
The sleeping position of the newborn is mainly determined by the caregiver. Generally, people in China think that children should lie flat as soon as possible, so they often take the supine position and fix their sleeping position with pillows, quilts and cushions, which is unscientific. The habit of Europeans and Americans is to let children lie prone, thinking that this will not affect the growth and development of children's brains. This has certain scientific truth, but on the other hand, due to the negligence of nursing, the rate of neonatal asphyxia is also high.
Sleep posture directly affects the growth and health of newborns. Don't fix your sleeping position, change it frequently.
Newborns still maintain fetal position at birth, and their limbs are still flexed. In order to help them expel some water and mucus swallowed in the birth canal, they should still take a low lateral position within 24 hours after birth. Sleeping in the lateral position not only oppresses important organs excessively, but also helps to relax muscles. In case of galactorrhea, the baby will not choke the trachea, which is a sleeping position for children that should be advocated.
However, the cranial suture of the newborn is not completely closed. If you sleep in one direction all the time or often, it may cause skull deformation. For example, lying on your back for a long time will make your child's head flat, and lying on your side for a long time will make your child's head crooked and affect your appearance.
The correct way is to turn over the baby frequently, change the posture and sleeping position, lie on your side instead of supine after breastfeeding, and avoid spitting milk. When lying on the left and right sides, be careful not to press the child's helix forward, otherwise the helix will often fold and be easily deformed.
Some incorrect sleep methods:
Sleep with your nipples.
Sleeping with a pacifier will make the baby suck after waking up. This irregular diet is easy to cause gastrointestinal dysfunction, and it will also cause poor breathing, leading to restless sleep and even suffocation. In addition, it also affects the normal development of gums or is prone to tooth decay.
stay up late
Some parents have the habit of staying up late, and the baby will stay up late. Because the peak of growth hormone secretion is at night 10- 12, if you stay up late, your growth hormone secretion will decrease and your height will be affected.
Scare the baby before going to bed
For children, sleep directly affects their growth and development. Mothers must pay attention to the baby's sleep, correct incorrect sleep methods, and don't say anything that scares the baby. Some mothers often scare their babies into going to bed as soon as possible, such as "the wolf will come without sleeping". In fact, this method will strongly stimulate the baby's nervous system, so that he can't sleep at all or can't sleep well. After the baby is threatened, it will have nightmares during sleep, and the quality of sleep will be greatly reduced.
Shake the baby to sleep.
When the baby is crying and unwilling to sleep, some impatient mothers often pick up the baby and shake it, shake it, or put it in the cradle. In fact, falling asleep like this is potentially dangerous. Because the baby's brain is not fully developed, shaking will make the baby's brain shake constantly in the skull, leading to the rupture of small blood vessels in the brain and intracranial hemorrhage, ranging from mental retardation to limb paralysis and even death. Even if the above situation does not happen, the baby will develop a bad habit of not shaking and not sleeping.
Accompany sleep
Some mothers like to sleep with their babies. Sleeping with them for a long time will develop the baby's "Oedipus" psychology. If parents don't sleep well, they will toss and turn in bed after falling asleep, and occasionally they will press the baby's face, causing a "tragedy" of suffocation and death.
Sleep with your head covered.
In winter, some parents are afraid that their babies will catch cold easily, so they sleep with their heads covered. The metabolism of infants and young children is far more vigorous than that of adults, and the humidity in the quilt is high, which makes the baby sweat, even collapse and breathe poorly.
Sleep electric blanket
The electric blanket heats up very quickly. If the temperature is too high, the baby will lose water and dehydration, which will cause the baby to fidget and cry, which will damage his health.
Sleep with the light on in the bedroom.
Some parents are used to staying up late and like to turn on the light very brightly, which is very unfavorable to the baby who sleeps in the same room. Infants have poor adaptability to the environment. If the lights are bright at night, the baby's sleep time will be shortened, which will affect the secretion of growth hormone and inhibit growth and development.
