Jill discovered a Bandaid stand-in:
I have a two year old with constant "boo boos" that need bandaids to get better. Few of these are actual wounds, but all of them need some love for recovery. Since real bandages aren't cheap, when the wound is invisible, I use all the freebie mailing labels I have instead. They seem to still make it better- in fact he's asked for them when Teddy Bear gets hurt too.
