Sleep of a child: from birth to 6 months
There is no sleep schedule for newborn kids, as their internal clocks work differently. Usually they sleep for 16 -20 hours a day. Most infants awake every 3-4 hours because they get hungry.
At the age of 3 months, a baby begins to sleep about 5 hours during the day and 10 hours at night, usually with some interruptions. About 90% of babies in this period sleep through the night for 6 - 8 hours without a break.
It’s important to know that babies aren’t always awake when they cry; they can cry and make all sorts of other noises during light sleep. Even if they do wake up in the middle of the night, they may only be awake for some minutes and then fall asleep again on their own. It’s best to learn babies early to get themselves to sleep.
If a baby continues to cry, it’s already time to come to it. Your baby may be sick or just uncomfortable: hungry, wet, cold or frightened. But you should shorten this time as much as possible and it is not worth talking, playing, or turning on the lights. Try to encourage the idea that nighttime is for sleep only.
It would be ideally, if you place your baby in the bed before he falls asleep. Remember that it’s never too early to establish a simple bedtime routine. Your baby will associate these activities with sleeping, and they’ll help him to fall asleep.
