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)

I don't normally write reviews but want to encourage others. Kid is 4 years old and had a crazy mouth fixation. If they weren't biting their nails they were resting with their hands around their mouth somewhere somehow. This immediately stopped that behavior and they slipped up a few times but now after using it for two weeks daily I stopped and its been over a week with the nails looking very healthy and no more hand near the mouth. Help your kid out, frame it that this helps the nails grow out healthy not that its a deterrent. Hope this helps someone out there on the fence!

My wife has a terrible anxiety habit of biting her nails until they bleed and it was her suggestion to try this out and it worked. She doesn’t even realize when she’s doing it * Subconscious action (in the past) but now with the stuff on her hand, she realizes it and realizes quick and stops biting 5 stars

A literal miracle cure! I did one application of this polish on all my daughter's fingers and within 48 hours she stopped sucking her thumb! Insane that it worked as she has been addicted to thumb sucking since a baby.

Thumb sucking? This nasty polish never heard of it. 10/10 tastes so bad and the taste last so long I only had to apply once. My daughter is 16 months and a comfort sucker, her thumb is so rough and dry due to this I tried gloves first but as soon as the glove came off to clean, the thumb went back in. Downside to this the first day it was so strong and she was trying so hard to suck her thumb she started drooling bc it tasted so bad and eventually threw up a bit because of it. And the taste transferred to cups from her mouth for two days so i kept washing the cups and gave her a wet rag to get the taste out. After that she hesitated to put her thumb in her mouth and a week later her thumb isnt even a thought. She switched to blanks for comfort. Use with caution, apply lightly!

Worked for my 5 year old to stop sucking his thumb. It tastes so bad. Only had to apply every few days then once a week. He quit in a few weeks. He wanted to quit so allowed me to put it on.
