Breastfeeding
Breastmilk is the best food for most babies.
Breastmilk contains all the nutrients a baby needs
for healthy growth and development during the first
six months of life, as well as substances that help
protect a baby from many illnesses. Breastfeeding
provides health benefits for the mother, including
that breastfed babies are less likely than formulafed babies to have ear infections, lower respiratory
infections (such as pneumonia and bronchiolitis),
meningitis, urinary tract infections and diarrhea1.
Studies also suggest that breastfed babies may be
less likely to die from sudden infant death syndrome
(SIDS)1. Breastmilk is easy for a baby to digest, so
the baby may have less gas and discomfort than a

What are the benefits of breastfeeding for
the baby?
Breastfeeding also may enhance brain development.
Some studies suggest that children who were
breastfed may score higher on tests of cognitive
ability than children who were fed formula1.
Breastmilk provides the ideal amounts of protein,
sugar, fat and most vitamins a baby needs for
healthy growth and development. Breastmilk also
contains substances called antibodies that help
protect a baby from many illnesses. Studies show
