What are you all doing about children with runny noses? Are you excluding them?

I've got 2 who have got runny noses at the moment. They're both perfectly fine apart from that - no temperature, eating & drinking as normal, playing happily.

We were talking in our local online group last night and one of the childminders said she's excluding children if they have a runny nose. A few agreed and said they would as well. I thought I'd read somewhere that if a child has a runny nose (or some other symptoms, but not the main covid ones) you can suggest parents might get them tested, but you can't insist on it or exclude the child. Now I don't know where I read it.

What are you all doing?
