I just posted this in a comment at Apartment Therapy, but I wanted to mention it to you, too:

When Becca had her surgery in December, she came home with Steri-strips over the incision. After enough time had passed and the Steri-strips were starting to come off, we used Tea Tree Oil to get them completely off. I think it would also work to take Band-Aids off with less pain and yelling. [FYI: It's also really good for shaving and for cradle cap.]
My friend Cayce told me the best thing of all about Tea Tree Oil: look for it in the black haircare section of the drugstore. It costs about half as much there as it does in the hippie section of the store.
