Honest10 Nail Biting Prevention for Kids & Adults - Break The Habit - Safe Bitter Nail Polish Formula, Lab Tested & Pediatric MD Approved - Thumb Guard, Easy Application, Made in USA (0.25 oz)

This is a great product! My son is four and he is a thumb sucker. Well, we decided it was time to stop because it was starting to affect his teeth. In just a few days of applying this to both of his thumbs, he stopped sucking his thumb. He even tried scratching it off but the awful taste was still there. It’s been about a month and he is still not sucking his thumb!

I put this on my three year old ONCE. it has long since come off and he doesn't bite. I tested it out myself and it's yucky. Wobya it works.

It’s working amazing , now my kid stop nails bitting .. I would strongly recommend

Amazing product!!!! My son has been sucking his 2 fingers since he was 6 months old. He is almost 4. I put this on his 2 fingers and he was soo disgusted by the taste that he gagged and ended up throwing up. The fear of throwing up again has made him never want to put his finger in his mouth again. All from that first application. It has now been a week of Noo finger sucking! So worth the purchase!

Well, it did the trick. My almost 3 year old has been getting chronically sick and we know sucking her fingers doesn’t help. We tried to replace the sucking finger behavior with other things but to no avail. This worked within 2 days. I applied another coat after a bath because can come off a little easy if you’re constantly wetting your nails. My daughter has a very sensitive gag reflex so the first time she sucked her fingers she gagged and almost threw up.. so I put some on my fingers and man is it NASTY! So go light on applying the coats because it is very strong and can leave the taste even on your lips. Highly effective, disgusting, but gets rid of a habit that helps them stay safe from excessive germs!!!
