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.
It depends on the age and the child itself but on average, newborns should sleep 12 to 18 hours a day, toddlers (ages 1 to 3) should sleep 12 to 14 hours, 11 to 13 hours for pâ¦reschoolers, and 10 to 11 hours for schoolchildren ages 5 to 10. Sources: New York Times.
