dd aged 4 has been out of sorts today, seemed tired, which we'd put down to a long week at school with first nativity etc and her waking a bit early today. After lunch she started complaining her tummy hurt, seemed a little hot and tired. She napped earlier and didn't really get excited about putting up the Christmas tree. Not constipated, not painful to wee, not feeling sick. Pain itself seems to have eased a bit now and she is now in bed although she gagged on first spoon of Calpol.
Any ideas what may be causing it ? Could she just be overtired.
