I don't think it's fish and milk because I have always fed fish fry and milk rice to my daughter and nothing happened. May be some indigestion, you can give ondem for vomiting.

Okay thank you

Fish and milk is always avoided in our place as it causes indigeston...even me as an adult have suffered when I had consumed in a lesser time gap..<br> As of now give enough water and nimbu pani , should be fine soon...
