(Younger babies with smaller tummies take less milk.) Breastfed babiesâ milk intake doesnât increase from months 1 to 6 because their growth rate slows.4 As growth slows, breastfed babies continue to get bigger and heavier on about the same daily milk intake, averaging about 25 ounces (750 mL) per 24 hours.
Women who are breast-feeding use about 500 calories daily to make the full amount of milk most babies need from birth to 6 months. Two-thirds of those calories should come from meals and snacks containing foods from all five food groups. The remaining calories come from the weight gained during pregnancy.
