My 4yo picked up the stomach bug from his siblings on Saturday morning. He was okay then sick again Sunday night, then fine eating more and then sick again last night. The rest of us got over it fairly quick. So that's 4 days of on/off being sick. Wants to eat, although not quite got full appetite yet. I read it should stop after 1-2 days. He hasn't had diarrhea. I guess at least it's not constant but I'm still worried. Normal? Thanks
