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.
1-3 Years Old: 12 - 14 hours per day. As your child moves past the first year toward 18-21 months of age he will likely lose his morning and early evening nap and nap only once a day. While toddlers need up to 14 hours a day of sleep, they typically get only about 10.n fact, they tend not to have much of a pattern at all. 1-4 Months Old: 14 - 15 hours per day. By 6 weeks of age your baby is beginning to settle down a bit, and you may notice more regular sleep patterns emerging. The longest periods of sleep run four to six hours and now tends to occur more regularly in the evening.
