How Much Milk do Babies Need?

Many mothers wonder how much expressed breast milk they need to have available if they are away from baby. In exclusively breastfed babies, milk intake increases quickly during the first few weeks of life, then stays about the same between one and six months (though it likely increases short term during growth spurts).

Current breastfeeding research does not indicate that breast milk intake changes with baby’s age or weight between one and six months. After six months, breast milk intake will continue at this same level until – sometime after six months, depending in baby’s intake from other foods – baby’s milk intake begins to decrease gradually (see below).
