My son is 14 months old n from few days he is not eating food properly any one can suggest what to do?

He must be teething. Let him eat whatever he wants to. Don't force. Children do feel uncomfortable when they grow teeth.

Hey try different recipes khichdi , kheer or smoothies ...
Teething might be the cause..

Happens sometimes with kids.. also it’s summer so appetite is affected... give milk or lots of liquids to keep baby hydrated... make meal time a fun time
