Mavala Stop Deterrent Nail Polish Treatment | Nail Care to Help Stop Putting Fingers In Your Mouth | Bitter Taste| Easy Application | For Ages 3+ | 0.17 oz

I work with two kids, aged 3 and 4, and their parents were struggling to get them to stop thumb sucking, it was affecting their teeth and just gross in general. Applied this stuff one time and I haven’t seen them suck their thumbs since! The younger kid likes having her nails done and happily lets me apply it, the older one complains because she knows it tastes bad but I get it done anyway and then she doesn’t suck her thumbs anymore. It’s been a couple weeks and I have reapplied the polish every few days to help make sure the habit is broken, but even after the first application I noticed them go to suck their thumbs, make a gross face, then stop and redirect behaviour. Accidentally got some on myself and tasted it and it tastes HORRID, a weird chemical taste like you just licked bug spray or something, and it lingers a bit. I don’t feel cruel for using it, the kids get over it quick enough and it’s a better behaviour enforcement than watching them like hawks and telling them to stop every 10 minutes.

Wow! Product was recommended by dentist. My 6y son would suck on his fingers and bite his nails. After only ONE use he has stopped. Wish I found this earlier. Very happy with purchase. Taste is strong but that’s the point. Work wonders

Great product but sometimes when I eat food my mouth gets all bitter because of my nails.😂

Bought it when my son was 3 to stop his thumb sucking. I’ve been using it on and off for 2 years. My son stops sucking on his thumb when I use this. I have to reapply every 2 nights. I do it while he sleeps. Then when I forget he starts again. So it is not a long term remedy but short. At least with my son. Make sure you close the bottle really well or else it will dry out and will become impossible to open it

This anti-nail-biting nail polish does exactly what it promises—it works! The bitter taste kicks in immediately if you try to bite your nails, and it's strong enough to stop the habit in its tracks.

Purchased to stop thumb sucking and finger skin bitting for two separate children. At first (few hours) stopped thumb sucking but then did nothing with more applications.Helped finger skin bitting but would get in child’s mouth when eating etc. child hated the taste and said it helped. Wish our issue was just at night.

My 3.5 year old was a chronic thumb sucker. Literally every time we read a book, watched a show, snuggled together, or she was just bored, the thumb would go right in. We painted this on her thumb literally ONE time almost a week ago. She made the mistake of putting the thumb in her mouth only three times that same day. She hasn’t even tried to suck since then, and we haven’t had to paint it on any other times. I’m sure it must taste awful, which I do feel bad about, but it worked! Obviously we also reinforced the good behavior with lots of praise and some rewards, and we’re still working up to a big reward if she can go a whole month without sucking, but the first step was made much easier and quicker with this product. Would recommend it to anyone.

Great product! Works very well. ONLY problem is with the screw on lid. I've had to purchase this product 3 different times because after using once the lid gets stuck. I initially thought it was because it had been stored on its side but I haven't done that with my last 2 bottles. Thought it might be that I got some of the liquid down the side when I was putting it back on with the last bottle but this recent bottle was used once (just about it 2 months ago) and I was extremely careful to make sure I didn't get any along the screw on part but the cap was so stuck that it broke when I used to pliers to open it. Would love if this problem was fixed. Going to see if I can someone get a replacement cap because I really don't want to buy it a 4th time.
