yes u can , but some time only

my daughter is 3 month I giving her Buffalo milk ...and wat quantity

you can give organic/raw cow milk & milk products,not pasteurised milk products

At this age baby's need anywhere from zero to one glass of milk. You can also give milk products like curds lassi paneer and a little cheese.

Hi Megha. Yes you can. At this age your child can have whatever you have. If you are giving for the first time try giving few sips to begin with so your child develops taste. I gave cow's milk on completing 1 year.
