DD (Year 5) was sent home on Wednesday after being sick once at lunch time. She said that she ate quite a lot for her school meal. She was absolutely fine after I took her home, and even managed to eat dinner. I kept her off today as I wasn't quite sure, but she has been fine all day and not thrown up since. She hasn't got a temperature and is begging to go to school tomorrow. Except that it wouldn't quite have been 48 hours. Should I do it?
