My son did not wake up this morning until 9:30, with help from me. This is not normal. However, I didnt really think much of it. During breakfast he didnt eat anything, also out of the norm. I let him out of high chair and thought maybe he needed some time before eating breakfast. About 30 minutes later he threw up all over the floor. It looked like curdled milk. After he threw up he seemed fine but was tired. I put him down for a nap and he was out. Is this normal? He has been on whole milk for about a month now and has had no reaction. I did however change to organic mild. Could that be the problem? I have been doing some research and read that I could be giving him too much dairy. I am not sure what to think or do. Your help would be greatly appreciated. Thank you! Stacy
