I recently had one of my boys with a scrape just below the knee that needed bandaging. Of course the bandage slipped without fail. Grr. Finally we just started to wrap above the knee which kept it from slipping down and kept the bandage where he actually needed it and not on his darned ankle! LOL
Oh, he also hates to have that leg wrapped now, even though the wound is gone.. big baby! He holds it up for me haha.
