Will giving a bottle at bedtime make my breastfeeding baby sleep longer?
Some babies sleep longer after getting extra milk at bedtime, but others do not. If the baby does sleep longer after a bedtime bottle, the mother’s breasts may become overfull and painful, and the pain may wake them before the baby does. Mothers may have to express in the middle of the night because the baby is unwilling to breastfeed after having the bottle. And if the baby wakes soon after expressing, mothers may not have enough milk available in the breast, so the baby will have to bottle-feed after breastfeeding, creating more work. Getting out of rhythm with the baby results in more expressing and bottling, and possibly a decreasing milk supply over time and a baby who is reluctant to continue breastfeeding. Overfull breasts can also lead to sore nipples, plugged ducts, and breast infections. In short, bedtime bottles may create problems and not give mothers any more sleep.
