Question: how many ounces of formula for an 11 day old?
Answer: Newborns start out with a stomach that can hold only a small amount at first. One to 2 ounces per feeding is usually enough early on, but by the time your baby is 2 months old, for example, she'll need 24 to 32 ounces a day and about six to seven feedings in a 24-hour period.
