Mavala Anti Nail Biting Formula
My daughter hates it, I love it.  Her nails have grown so much since putting this on her. We have a deal that I get to choose which 4 nails to put it on, while she hides her eyes.  I put clear nail polish on the other 6 fingers.  She hates it so much that she doesn't go near any of her nails just to avoid the taste, but at least this way she has less of a chance of an accidental tasting.  You know, when eating chicken wings, etc.
