My 7yo son had chicken nuggets at BBL cricket game on Tuesday night. At lunchtime today (Wed) our family arrived at the cinema for a movie when our son said he was going to be sick (He had been quiet most of the morning). He went outside and vomited in the rubbish bin. I took him home and he has been vomiting every 1-2 hr since. Last couple were just liquid and he is starting to feel a bit better (now 10:30pm).
