8months old baby can't eat she hates food why and not gain weight only her 6.5 kg only why

A. This is very common problem when baby switch from breast milk to semi solid or solid diet they take some time to adjust so do not worry try to introduce more variety let him play with his plate try to divert his attention like you can put some toys around him and put bites in his mouth you can offer him food in Puri form or finger food also
