Quarantine??

I know you're probably all tired of listening to me whine and moan about my issues, and even my DH says I'm looking for trouble. So I'm trying to take advice of others to heart, and thank you all for your advice and comments (either through the blog, or emails). L's ear feels fine to him so far, after almost a week of being on cefzil (I think that was the name), but we will take him to the germ factory otherwise known as the clinic to get his ear looked at again on Monday. (And he will be instructed to NOT TOUCH ANYTHING while we're there!)
This weekend I'm hoping to accomplish a lot of my To Do list, providing no one gets sick, that is. And speaking of that, is it weird that I want to encase my family in a giant plastic bubble for the week? All I've heard lately is "this person is sick" or "my friend's kid is sick" or "we were all sick last week" from everyone I talk to as well as friends' postings on Facebook.
Ugh.
To top it off, one of the girls I look after, S, was up all night last night puking, dry heaving and crapping. Oh god. She was here, at my house, ALL DAY yesterday! It totally makes me want to go bleach my whole house. Instead, I'm sitting here blogging about it. Not that I have a choice, I have three kids under 3 today, so it's not like I can leave them unsupervised while I go upstairs and disinfect for the next two hours. But mark my words, I will be doing some of that for sure once they're in bed. Thank god for naptime!!
The three toddlers in question have colds now. I've been wiping their noses all week. I don't know if this is the cold I had the week before, or a new one. I wish there was someway to tell, like some sort of colour-coding to the snot pouring out of their noses.
"Oh I see J has blue snot, that's the same as M and me last week, but C's is purple so that's a different virus."
That would be kinda handy. At least I'd know I was either fairly safe from getting it again or quite likely to get another virus.
So the question is, what next? I seriously want to keep my kids away from all other children and dirty contaminated surfaces for the next week. It makes me want to pull them out of school for the start of next week. But considering they're already going to be missing a week of school already, I'm not so sure I should. Maybe the teachers could send their work home to me? Hmmm... However, I'd also need to close the daycare in order for us to truly be quarantined and that's not going to happen so ingress there's not much point. Only at home, I can nag them more about washing their hands. So, what to do, what to do…
