Newborns aged 0-3 months need 20 hours of sleep per day The above sleep time is the sum of [several naps during the day] and [long sleep at night]. As an example, for a one-month-old baby, 12 hours of continuous sleep at night, 3-4 naps during the day plus always 8 hours, for a total of 20 hours. Daytime naps, no more than 3 hours per sleep period When your baby naps for more than 3 hours during the day, make sure you always get your baby up for milk! Unless you’re lucky and you’re still a super-sleepy newborn under a month old, you’ll soon learn the hard way that the consequences of day-night disruption are waiting for you. Don’t be afraid to wake him up, don’t worry about getting your baby up so it’s not good for your baby, it’s the day and night reversal that violates the physiological clock that’s bad for your baby! Of course, there is still some flexibility in the implementation. Don’t let your baby stay awake for more than 3 hours in a row. Your baby’s brain is still developing at this stage, so it’s not good to stay awake for too long and not rest your brain for a long time. Don’t feel as if your child is “in good spirits” or “doesn’t want to sleep”, but those are all illusions! It’s up to parents to guide their children, not to let their increasingly playful children dictate their routine! Please set 12 hours for long sleep at night. Please don’t doubt that every baby has the potential to sleep for 12 hours at night. No need to doubt! No need to doubt! No need to doubt! Let your child sleep with confidence! Conclusion: First of all, new parents should keep in mind that babies are human beings, not machines! Since they are human beings, they should naturally follow the laws of nature, not just feed according to their own subjective judgment!
