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.
Time to lengthen awake times or times between feeds (or both!). Tracy Hogg in The Baby Whisperer suggests that a 4 month old should be on a 4 hour routine. That means that every 4 hours, the routine is repeating itself. For example, wake for a feed, 2 hours awake and then two hours asleep.
