Wish I could help you. Since my 4 1/2 year old daughter stopped sucking her thumb about a year ago she's picked up the habit of picking at the skin on her top lip to the point that it bleeds sometimes. I bought her some special lip balm and Tinkerbell lip gloss thinking that might help and it did, but only temporarily. It's been really cold here lately and it's also hard to get my daughter to drink enough liquids so her lips get really dry and that makes her pick at her lip even more.
