5 year old DD was tossing and turning all night last nights with what seemed like a cold. Had calpol this morning and seemed much better, running round with sibling etc. didn't eat her breakfast as she said her tummy hurt but that was all that seemed to be wrong so we sent her in to school. She got sent home as she was apparently sick once at lunchtime, since being picked up she has eaten and has kept everything down but has a low grade fever. However she keeps saying that her stomach is really sore, every time she drops off to sleep she wakes up crying that the pain is really bad. Anyone have any idea what it could be? I'm thinking it's not a sickness bug as she's only been sick once but have no idea what would cause stomach pain and fever!
