my baby is 7 month old she is having solid food for 2 times and also having brest milk but she is not gaining her weight....how to gain her weight

A. If The weight is not increasing then apart from breastfeeding start giving formula feeding or tone pasteurised milk to your child that is going to help and apart from that also I would like to tell you that sometimes even what you are giving a child is not eating it good quantity that also hampers the weight
