I have a six year old. Every so often he wakes in the early hours of the morning randomly vomits for a few hours where he can't keep stuff down not even water. At about 9/10am he's absolutely fine. No other symptoms. This happens about 4/5 times a year. At first I though he was just hungry so I started given him a light snack before bed. I've brought him to the doctor who said it's nothing to worry about. The problem is I can't send him into school when he's sick so he's missing a fair bit over this. I've said it to a few mums but none of them have ever heard of anything like this. I don't think it's a bug as all the times he's been sick none of us have been sick either and he has no other symptoms. AIBU to think this isn't normal and should I be pushing for tests to get done?
