my baby is 23 months old, he didn' t eat food and become very weak which vitamin should I give to my baby please tell me

A. Hai good morning !! If baby is active but not eating food properly means check his appetite .. Sometimes outside ,packed/processed foods,sugar,oil cause less appetite,worms in stomach also cause less appetite. Give timely feedings 3 meals 2 snacks fibre rich foods finger foods fruits,boiled vegetables as snack,dals,kichdi,curd rice ,roti,parantha.... Helps in easy digestion,good metabolism . Avoid breast feeding ,packed foods give more water,fluids..
