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.
Discover the hows and whys so that you can get back to those restful nights. Newborns less than three months old sleep between 14 and 17 hours each day. As few as 11 hours and as many as 19 hours may be appropriate. Infants (between 4 and 11 months old) sleep between 12 and 15 hours each day.
