Lactose intolerance

We have suspected for a while now that Nicholas may be lactose intolerant. He was able to tolerate formula just fine, but for some reason, he started getting really sick in January. He would throw up after drinking milk. He also had a fever and diarhea so when I took him into the doctor we assumed it was some kind of stomach bug. Well, it lasted about 4 days and he was fine again. In February, he got sick again, but so did the other kids. It started with pink eye and then Devan got laryngitits... I spent so much time in the doctor office, that when Nicholas got sick again, it was easy to just say that the whole family is just having a rough month. So, his doctor stated that it may be necessary to see a GI doc if it doesn't clear up. Well, it did and it started again in March. I am getting concerned at this point, and I called the GI doctor that helped Devan when he was 2. He needed a referral from our regular doctor and was completely booked up until after April 10th well, I was not able to get in to see his regular doctor by then and of course he wasn't sick at that time.

Well, when he got sick again this last weekend for no apparent reason, I decided to get the next available appointment with this doctor to get the referral to the GI doctor just to get it checked out and tell someone (who may have an idea what I'm talking about) what has been going on. Well, I will have to update later as to when and if I can get in with the GI doc any time soon, and if so, what he says, but for now, here is a picture that shows how yucky Nicholas has been feeling.
