This might sound really stupid, but I think the difference is that while we as adults DO care about sharing drool, babies DON'T! I know we're in charge of making those decisions for them, but TBH, I don't want to spend every playtime monitoring what goes in my DS's mouth, and taking it off him if it's not his. Equally, I'm not about to say that we're not sharing his toys with other babies.

Having said that, I'm in the same boat as Cai..........I'm happy that the people we spend time with are not knowingly taking their babies out and about when unwell. If I thought they were doing that, I probably wouldn't go. I know that you can't always know when a kid is infectious, but that's just life, isn't it. We have to take 'risks' or we'd have pretty boring lives IMO. But knowingly sharing germs is another thing
