Jessica is a nail biter. Not only does she bite her nails to the quick, she chews the flesh along the nails. Being a mostly recovered nail biter myself, I can sympathize.
A few days ago I was in Walmart near the cosmetic section. I saw the nail polish and had a flashback to the summer I was 10. I remember it vividly. We were on vacation at the Jersey shore. My mother wanted me to stop biting my nails so she told me if I did, I could paint them. Mom may deny any recollection of this, but if I say it was the vacation where she got a bug in her ear, I'm sure she'll remember that.
Anyway, it worked. Not soon after my nails grew long enough so I could paint them.
So, I saw the nail polish and a more modern invention: nail decals. I bought some of each and told Jessica when she stopped biting her nails she could paint them and put decals on.
Every day since then, she pushes her grubby little fingers into my face and says, "Can I put on nail polish now?" So far, I've denied her but she is showing a visible improvement. Fingers crossed that Mom (my mom) knew best.
