Well established breastfeeding means that:
Your baby can easily put his or her mouth around the nipple and latches on
Breastfeeding is comfortable for you
Your baby weighs more than his or her original birth weight
These milestones are usually reached after the first 3 or 4 weeks.
Getting started with breastfeeding
Your milk and how you breastfeed change as your baby grows and develops. A newborn’s feeding routine is different than that of a breastfeeding 6 month old. As your baby grows, the nutrients in your milk adapt to your growing baby’s needs. The anti-infective properties also increase if you or your baby is exposed to some new bacteria or virus.
