How many hours a day should a newborn sleep?
Q: How many hours a day should my 4-week-old baby sleep?
A: There is incredible variability in how much newborns sleep, ranging from as little as 10 hours to 18 hours a day. As your baby gets a little bit older, usually by 8 weeks or so, expect more predictable sleep patterns to begin to emerge.
