my baby is 21 month still eating semisolid food not eating chapati ,bhaji etc his weight 10kg not increase from 2 months

A. To understand this thing that in the initial is kiddos do not have have teeth which is why we advised to give food like that but with progressing when you have to teach them to choose the food otherwise the food is going to get digested it is going to come out and motion the same way which is why probably a child is not gaining weight also
