My baby is having milk from last 3 years but suddenly she has started complaining about stomach ache. she also suffers from loose motion and vomit very frequently. Now, while she is suffering from loose motion, when we gave her milk and ice cream, she vomits. We have stopped giving her milk but how she will manage to get nutrients which milk gives. I am in confusion whether to give her milk or not. I also feel afraid if I will give, she will vomit or not. please advise.
