My daughtet is 23 months old. when i tried to give diluted cows milk she got constipated. Can she not be able to drink cows milk. What is the alternative for cows milk

A. Buffalos Milk you can try also you can dilute it like one fourth of water and one KG of milk I think that would be the right proportion apart from that I would just like to tell you if buffaloes milk is also not suiting the child then you can switch to either tone pasteurised milk or full cream packet milk
