Question: how long should a one month old eat?
Answer: Newborns should nurse 8-12 times a day for the first month; when your child gets to be 4 to 8 weeks old, he'll probably start nursing 7-9 times a day. If he's drinking formula, your baby will probably want a bottle every 2 to 3 hours at first. As your child grows, he should be able to go 3 to 4 hours without eating.
