I wouldn't take my kids if i knew they were sick. Especially if they had a tempreture.

BUT, my DD had a continual runny / blocked nose for 6 months due to enlarged adenoids. It was not contagious. Also, some kids get hay fever and have a runny nose, again not contagious. So somebody looking at her might have thought she was ill. If you are concerned that another child is sick, ask the parent.

Its not nice when kids get sick but in reality evertime they come into contact with anybody there is a chance that person could be coming down with something and not even know. I try to minimise my kids getting the germs into their system, like with those disinfectant hand gels etc, but kids will be kids and they will get sick.
