4 months baby should give milk every two hours like a new born or give 3 hours

A. At 3 to 4 months old, your formula-fed baby will have around 32 ounces of formula each day over five to eight feedings of 4 to 6 ounces each. (See whether your baby is getting enough formula.) If you're breastfeeding, your baby will eat five to eight times a day, every two or three hours.
