my baby weight birth was 3.4kg now she is 5th 5kg only not looking weak..how to gain weight

A. Ur Baby has gained about 500 g in a month or in totality 5C 1 1/2 KG in four or five months is really very less it should have been somewhere around 2 1/2 to 3 KG is in the gap of five months so you know so you should start with formula feeding I think you’re breastfeeding is not sufficient for the child
