If he's in the middle of his cold, I wouldn't take him to playgroup or ABA meetings.... I like to consider the other parents and kids. But in saying that, it's hard to know when your LO is infectious and when they aren't! After all, some kids can be spreading cold germs when they don't even present with symptoms themselves? so it's a hard one.

If his nose is running badly then yes I would stay home. It's hard though esp when you want to get out of the house!

Good luck
