my kid is 2 years old. till now I hv been giving him formula milk (nan pro 4) once a day. Apart from regular food, he takes milk atleast 3 times....out of which 1 time I give formula, rest 2-3 times it's cow milk. should I stop it now....(as it says upto 24 month) or shift it to some other formula milk/food....or continue with the same. pls suggest
