Baby sleep basics: Birth to 3 months. Typical sleep patterns for newborns. Newborns sleep a lot â typically up to 16 to 17 hours a day. But most babies don't stay asleep for more than two to four hours at a time, day or night, during the first few weeks of life. The result? Lots of sleep for your baby and a very irregular â and tiring â schedule for you.
Between 9 and 12 hours of sleep per night, plus two to four naps lasting half an hour to two hours. Nap Strategy. Your baby will need fewer daytime naps as he gets older. It's helpful to be consistent (but not obsessive) with his schedule so he learns to soothe himself to sleep.
