Correcting the age of 1~2 months, babies sleep for an average of about 15 hours a day. Most babies know the difference between day and night, they have to eat milk every 3~4 hours, they can play for a while after eating milk during the day, and their life starts to be regular. However, due to different innate temperament, some babies still cannot sleep by themselves during the day and can sleep longer if they are held. They are used to adult embrace, next to the mother’s breast, and this environment he can sleep well. Parents worry that their children will develop bad habits if they are held to sleep. In fact, this worry is unnecessary because babies do not yet have the ability to remember and will not be spoiled. In order to allow the baby to sleep more, which is conducive to brain development, you can hold the child to sleep during the day, and at night, wrap the baby with a cotton wrap, which can make the baby sleep more peacefully. 3 months later, you can not hold the sleep.
