Hi.... Formula-fed babies need around 150-200 ml of formula per kilogram of body weight per day until three months old, then 120 ml per kilogram of body weight. For example, a one-month-old baby who weighs 4 kg might have 600-800 ml of formula a day or a 5-month-old baby who weighs 7kg might have 840 ml of formula a day.
