How much sleep does a 15-month-old baby need?

Sleep is a necessary way for the human body to get rest. Generally speaking, the amount of sleep a person needs changes with age. The elderly and young children need longer sleep, while young and middle-aged people need less sleep. A correct understanding of the necessary sleep time is beneficial to physical health. So, do you know how much sleep a fifteen-month-old baby needs every day? Let me give you an introduction below.

1: How to judge the baby's sleep time

Sleep can be divided into light sleep (active sleep) and deep sleep (quiet sleep). The younger the baby, the faster his brain develops and the more sleep he needs. Changes in infant sleep development are closely related to brain development. The brain of babies under one year old develops fastest, and changes in their sleep development are also most obvious. Sleep changes are manifested in a shortening of the total sleep time per day, a gradual lengthening of the sleep cycle, a relative reduction in light sleep time, a longer nighttime sleep time, and the formation of a circadian rhythm. Newborns need an average of 16 hours (14 to 20 hours) of sleep a day.

2. How long is the appropriate sleep time for babies?

At the age of 1, the baby sleeps an average of 13 to 15 hours a day. He can sleep all night until dawn, has long wakefulness during the day, and has 2 to 3 regular naps. There are great individual differences in the amount of sleep different babies need. If your baby cannot sleep for so many hours but is very energetic when awake, you don't have to worry about him not getting enough sleep, because the baby has no "learning or work tasks" and he will sleep naturally when he is sleepy. Some parents may worry that their children will sleep too much. In fact, as long as the baby reacts quickly when awake, his intellectual development is similar to that of children of the same age, and he does not show abnormal behavior, there is no need to worry.

After reading the above introduction, do you know how much sleep a fifteen-month-old baby needs? If your baby's sleep time does not meet this standard, it means that the baby's body has not gotten enough rest. If it exceeds this standard, it means that the baby may be malnourished. You can take your baby to the hospital for a trace element test.
