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.
What is too much sleep? When your baby is sleeping 13-15 hours per day, this is within normal ranges for a very long time. If your baby is sleeping less, this may or may not be enough sleep. Depending on your babyâs age, a typical baby will sleep 11-12 hours at night and 2-3 hours during the day.Since averages are just those, your baby may indeed need more like 12 hours at night and 4 hours of sleep during the day. This is unlikely to be a cause for concern.hat is too much sleep? When your baby is sleeping 13-15 hours per day, this is within normal ranges for a very long time.
