My 4 year old girl Zoe does this also. She has done it pretty much all of her life, no matter what food she has eaten and I buy quality brands. I have wondered if hers is a habit like biting nails and if maybe it is when her nails get longer. I wish I knew why also as it can drive you nuts when they are in bed laying up against you. I can sometimes get on to her and tell her to stop and she will quit. |
