Yes, I have a 3 1/2 year old son with cerebral palsy , spastic diplegia , and it started on Saturday. He was vomiting, but not alot. He continued to seem sick, and vomit maybe every 4-6 hours. He has not puked since yesterday morning, but now every time he burps it smells like rotten eggs or feces. Now he has diarrhea real bad. Is this something that will blow over, or should I take him in to see his doctor?
