Question: how much does your 1 month old baby eat?
Answer: During the first few weeks: 1 to 3 ounces of formula every three to four hours (this will probably be closer to 2 to 3 ounces a feeding after the first few days or week). Wake your baby for a feeding if he sleeps longer than five hours. By the first month: At least 4 ounces every four hours.
