My baby born with 2.480 kg weight.After 14 weeks her weight is 4.3 kg which is lower than ideal weight range.She is on 85% breastfeed and 15% on formula feed.Please suggest

A. hello the baby is gaining a minimum of 600 gram to 800 gram per month it is a good weight gain and absolutely nothing to worry and not a problem and just in the case the BM is not sufficient you can incase the bm is not sufficient you can alternatively give baby infant formula milk stage 1 using a bpa free bottle like babyhug which can help in the growth of the child
