Question: how much formula is too much for a 1 month old?
Answer: Most babies are satisfied with 3 to 4 ounces (90–120 mL) per feeding during the first month and increase that amount by 1 ounce (30 mL) per month until they reach a maximum of about 7 to 8 ounces (210–240 mL). If your baby consistently seems to want more or less than this, discuss it with your pediatrician.
