My 10 year old grandson ate an entire bag of cotton candy from local fun park. He ate a partial of the bag while there and within 30 minutes he ate a meal of crackers, chicken salad, pasta salad and gatorade for dinner. shortly thereafter, without my permission, he ate the remainder of cotton candy. when time to take him home to his mom an hour later, he was feeling nauseated. He has not thrown up, he has had normal poop, still feeling sick and rotating from nausea and sever head ache. Gave small amount of coke through straw to help, but no good. Now he is feeling worse with same symptoms. Has been feeling this way overall for 2.5 hrs. What do I do?
