However, many experts agree that the first few months after baby is born are vital for both mother and child. It is during this time that baby’s immune system is developing and they are getting all of the nutrients they need from their mother’s milk. Breastfeeding also helps to bond mother and child and provides a host of other health benefits for both parties. So while there may not be any definitive answer as to which months are the most important to breastfeed, the general consensus seems to be that those early months are crucial.
