Just went through the same thing - we have two grandkids that live with us, 7 & 4, both did the whole uri thing and they aren't good at covering either tho are better at covering now that we explained it could hurt grandpa worse to get sick. I encouraged lots of handwashing and germ-x which they think is cool. We got thru it without sending them anywhere. H didn't get sick. Believe me, I understand your concern.....my first few posts here were about whether we would have to send the kids away to get thru h's tx. I also became a clean fanatic with lysol and the wipes for hard surfaces. Good luck!
