For most of human history there has been just one source of nutrition for babies before weaning, that is of course human milk suckled from the breast. Only in the last 100 or so years have substitutes based on modified cows’ milk been available and even today, with all the science behind these, there is still overwhelming evidence and belief that breastmilk is the very best for the young infant. Breastfeeding is therefore the most natural and best option, and yet many modern mums either never start or give up before their baby is fully weaned.
