Breastfeeding is good for your baby and good for you. Breast milk has the right amount of fat, sugar, water, and protein needed for your baby’s growth. Breast milk contains antibodies that protect babies from infections. Breastfed babies have a lower risk of sudden infant death syndrome (SIDS).

For you, breastfeeding triggers the release of a hormone called oxytocin. This hormone makes the uterus contract and return to its original size. These mild contractions also reduce the amount of bleeding you may have after giving birth.
