For children, the quality of sleep is directly related to growth and development. On the one hand, sleep can relax the brain nerves, muscles and so on, to relieve muscle fatigue; on the other hand, after the child falls asleep, the body growth hormone secretion, which promotes the body to grow taller growth hormone secretion in the sleep state is about three times the amount of waking state, so sufficient sleep is very beneficial to grow taller. Therefore, it is very important to give your child enough time to have quality sleep. Sleep is directly related to growth and development Sleep plays a significant role in the intellectual development of infants. Scientific studies have found that blood flow to the brain increases significantly when babies are asleep, and sleep also promotes brain protein synthesis and the development of infant intelligence. If a baby sleeps well, he will wake up in good spirits and will be able to receive more information during the day. If he sleeps poorly, he wakes up in a bad state and is not easily receptive to things around him. At the same time, the growth of children is also related to the secretion of growth hormone. Growth hormone is secreted more and faster when sleeping, and quality sleep is very helpful to baby’s growth. If your baby does not sleep well, not only will he or she be easily irritable, but it will also affect normal eating. Doctors say that newborns born less than a month, sleep about 16 to 20 hours a day, usually sleep 1 to 4 hours will wake up for an hour or two, the total number of hours of sleep during the day and night is about the same; born one to four months or so of the baby, sleep about 14 to 15 hours a day, each sleep time about 6 to 8 hours; six months of toddlers sleep about 13 to 14 hours a day; and one year to three years old Toddlers sleep about 12 hours a day. Most babies can sleep through the night when they are nine months old. Of course, whether a child sleeps enough or not does not depend entirely on the length of sleep, but also on whether it has an impact on his length, development, and intelligence. It is best to measure the height and weight at the beginning of half a month to a month, and then once every two or three months to see if he is about the same age as his peers. Lack of sleep in infants will soon be reflected in development. Some abnormalities before and after sleep indicate that the baby may be getting sick The child is quiet and comfortable during normal sleep, with a slight head sweat and even and silent breathing. If there are sudden symptoms such as snoring and red face, it is likely to be a precursor of illness. Parents should not think that everything is fine when the child is asleep, but should pay attention to the child’s sleeping condition in order to detect the signs of various illnesses early. The doctor advised parents that there are many reasons why babies and toddlers are restless, parents should first pay attention to the following aspects: first, check whether the bedding covered by the child is too much; second, the air in the sleeping room should be kept circulating; third, if the child wakes up crying at night, it is recommended not to hold, and do not turn on the light, tap to give soothing. Fourth, around 1 year old, night milk can not drink, switch to drink a milk before bedtime.
