NoBite Nail Polish works
I was worried about my daughter developing thumb sucking teeth, and hoped the habit would just wear off with age, it didn’t. In fact, it only got worse. I didn’t want to spend a fortune on the Tguard. One day, I was putting my makeup on and my daughter came over, sucking her thumb. When she saw me applying makeup she came over and asked if she could put on some. I told her that I would, but I had to buy it first. Once I finished, I went onto amazon and bought the NoBite Nail Polish. When she came home and was once again, sucking her thumb, I told her I could paint her nails. I took her into the bathroom to put it on for her. Before I did, I told her she couldn’t suck her thumbs if she wore it. I put it on, and the habit was effectively broken.
