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.
How Many Hours of Sleep Does a Toddler Need? By the time a baby becomes a toddler, she will need 10 to 14 hours of sleep per day. This includes one nap (after 18 months, naps are reduced from two to one) that lasts about one to three hours. Keeping these numbers in mind, a toddler will normally sleep 10 hours or more per night.
