The following is an overview (not necessarily the same) regarding the number of hours of sleep for babies by age:
Baby 1-4 weeks: Sleep time 15-16 hours per day
Newborns usually sleep at least 15 hours per day, some even up to 18 hours per day. Meanwhile, babies who are born prematurely, usually have a longer sleep time. A newborn baby does not know the cycle of time, he does not know day or night, therefore, his sleep is not patterned, he may often sleep during the day or vice versa.
Infant 1 – 4 months: Bedtime 14-15 hours per day
At the age of one month’s baby, the baby has found a little sleep patterns. When sleeping, babies can spend 4-5 hours and it will usually happen at night. At this time the baby has begun to feel a little bit where night and day are.
Baby 4 – 12 Months: Sleep Time 14-15 hours per day
15 hours of sleep is ideal for babies of this age, but by 11 months, babies usually sleep about 12 hours. At this age, giving babies good sleeping habits is the main thing, because babies have started to interact and their sleep patterns can follow adults. If parents fail to adopt a good sleep pattern at this time, then the failed habit will carry over to the next big one.
Ages 1 – 3 years: sleep time 12-14 hours per day
At this age, your child has started to lose sleep patterns in the morning. They still sleep only once during the day, and continue at night. Children who still need a nap is usually between 21 and 36 months of age, and it usually takes 3 to 4 hours. At night, children usually fall asleep between 7 and 9 pm (depending on habits) and will wake up in the morning between 6 or 8 o’clock.
Ages 3 – 6 Years: Sleep Time 10-12 hours per day
Children at this age will go to bed at night starting at 7 or 9 and wake up between 6 and 8 in the morning. At the age of 3 years, some children still need naps, and by the time they are 5 years old, the habit of napping begins to be abandoned
