Well, years ago working in the daycare world I discovered a wonderful trick. Instead of trying to peal off sticker after sticker for the children, I would pull off the surrounding "waste" and it made it easier for those little fingers to get the stickers off.
Occasionally I would find they still had trouble. In most cases you can bend whole sections to the backing back a bit. Exposing the edge of the stickers.
It's been helpful, children get the satisfaction of being a bit more independent and I, I don't have to pick at endless sticker edges.
