I also just use one hand towel per day. I know licensed have to use paper towel or one per child but that just doesn't seem practical to me when I only have 4 and only 2 wash their hands (the other 2 I still use wet wipes on) I think of it like guests towels lol...I don't give each of my guests a hand towel to use for the evening! If they've washed properly than it shouldn't be a big deal....not much worse than them licking all the toys and passing those germs around anyways lol
The command stuff works great though!! We use them all the time too
Just saw Rachael's link...I have that too and it would work in the bathroom!
