Question: how much formula should a 6 month old drink with solids?
Answer: 6 months: Once solids are added to the mix, the number of formula ounces should be scaled back a bit. 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.
