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.
1 Infants 4 to 12 months should sleep 12 to 16 hours per 24 hours (including naps) on a regular basis to promote optimal health.  Children 1 to 2 years of age should sleep 11 to 14 hours per 24 hours (including naps) on a regular basis to promote optimal health.
