Babies at this age of months are equivalent to the neonatal period when they are born at full term. They sleep an average of 16 hours a day (14~20 hours). They don’t know the difference between day and night, and they need to be fed every 3~4 hours, so they have to wake up frequently to feed around the clock. They are accustomed to the adult’s embrace, next to the mother’s breast, and he can sleep well in this environment. The mother’s breast can be a comforting nipple that the baby can sleep with. Can also be used rubber nipple into the baby’s mouth sucking; this period if the hold when sleeping well, put to bed for a while to wake up, you can hold the baby to sleep during the day, the night with a cotton wrapper wrapped baby can sleep more peacefully.
