The continuous sleep time of newborns generally does not exceed 1 to 2 hours, and there is no circadian rhythm. Usually sleep 8 to 9 hours during the day and 8 hours at night.
As babies get older, their total sleep time gradually decreases. Slowly sleep shorter during the day and gradually lengthen your nighttime sleep. Most babies are not able to sleep for 6-8 hours at night until they reach 3 months (or when they weigh 5.5-6 kg).
About two-thirds of babies are able to achieve relatively regular sleep by the age of 6 months and do not wake up frequently at night. However, there are individual differences between children, and each child’s sleep pattern is different. For example, some healthy babies cannot sleep more than 6 hours at night even if they are almost 1 year old.
