Hi, my 10 year old daughter has recently had what seemed to be a stomach bug, but followed a very odd pattern. She awoke in the early hours of the morning and vomited a few times over a couple of hours or so and the following day seemed to be feeling much better, eating fairly normally. The next night the same thing happened, and now she is back to normal. So I was just wondering if a) this could just be the way her body deals with a virus or b) whether hormones could be causing this with her coming up to puberty?? We all had a bug last year and again her vomiting was following a similar pattern, over 4 days on that occasion. Thanks. Mrs Brown.
