Question: how many ounces of formula should a 6 week old baby drink?
Answer: At this stage your baby may be drinking up to 6 to 8 ounces of formula per feeding every four to six hours — but limit the total intake to no more than 32 to 36 ounces per 24-hour period. That's the upper daily intake for babies 6 months and younger, according to the American Academy of Pediatrics (AAP).
