Hello My name is Jen and I have a Son who is two years old. Recently he was diagnosed as Lactose Intolerant and put on a very strict diet. The diet is he can't have anything with lactose, he can't have juice or greasy foods. We have kept him on this diet watching him so carefully we locked the fridge door. The reason he was diagnosed with L.I. is because he had vomiting and diaherra for a month and they finally ran some test on him and kept him in the hospital for low potassium. MY Question is this..... He is still having diaherra and vomiting was he diagnosed wrong, should i wait longer for him to quit having diaherra and vomiting, or am I doing something wrong?? Please help us.
