My baby is 4months old. Is it necessary for baby to give formula other than breastmilk before 6 months?

A. hi dear That adds up to 24 to 36 ounces of formula in around six feedings total in a 24-hour period. 4-month-olds will often drink 5 to 7 ounces of formula every four to five hours. That adds up to 24 to 32 ounces of formula in four to six feedings total in a 24-hour period.
