Question: how many ounces of formula should a newborn drink per day?
Answer: How many ounces do formula-fed babies need each day? The American Academy of Pediatrics (AAP) explains that after the first few days, your formula-fed newborn will drink around 2 to 3 ounces (60 to 90 milliliters) of formula with every feeding. They'll need to eat about every three to four hours.
