hey, here's something she might love, and it makes her feel grown up, and may stop her! nail polish!!!! it's a fun way of trying to prevent it, because she will see how pretty her nails are, and if she sucks her thumbs, it'll wear off quickly, and she might enjoy the way it looks, and admire her nails instead of sucking the thumb. secondly, if you get the cheap nail polish, it usually tastes pretty nasty, thus making her not want to suck the thumn so much.
