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.
Since babies this age are more awake, alert, and aware of their surroundings during daylight hours, they're more likely to be tired at night and sleep. But the range of normal is still very wide. By 3 months of age, babies tend to sleep about 14 hours a day. Many will have settled into a daily sleep routine of two or three naps during the day, followed by sleeping through the night stretch after a late-night feeding. Again, not all infants keep to the same timetable.
