what is the right age to start Bourvita, Horlicks.. etc my baby is 1 yr 4 month, she has started refusing milk( cow milk)

A. Cow's milk should be given to the baby only after completion of 1 year of age because the protein and fat in cow's milk is hard to digest before that and many a times there could be cow's milk protein allergy in babies and lactose intolerance which could be severe sometimes. Also early introduction of cows milk can lead to iron ddeficiency afnemia as cow's milk lacks iron and vit c . Also there could be micro bleeding in intestine because of the heavy protein of cow's milk .
