Thank you

Em, shes had the cold since sunday. Sunday and monday were the worst days, yesterday and today she still has a 'little sniffle' according to her. Shes wiped her nose a few times today, but she sounds really sick thanks to losing her voice!
She is the same as Tanstar's DD, she could still have a runny nose for a couple of weeks, but be fine in every other way. Thats why I ask. I cant stand it when parents send contagious kids to care, and I dont want to do that. But at the same time what is considered contagious?
