If mother's milk is not sufficient for a 1 and half month old baby, what is the best supplement one can give? Also which is the best supplement to boost mother's lactation?

A. The lactation is depends on the feed baby takes, more the baby sucks and take the feed the more milk will produce automatically. It's a natural process and baby needs more breastfeeding then any other milk at least till 6 months. Still you take good iron-protein diet and protein powder to increase breastmilk
