Question: how long can a 2 month old sleep at night without eating?
Answer: In fact, two to four hours at a time is about as long as you can expect your brand new baby to sleep during those early weeks and months — depending on whether you're breastfeeding, formula-feeding or both. 2 to 3 months old: 2- to 3-month old babies can sleep for five- or six-hour stretches.
