NIXXIT Nail Biting Prevention for Kids - Thumb Sucking Deterrent for Kids, Toddlers, Children - No Bite Nail Polish Pen - Bitter Taste - Safe & Effective Solution for Age 3+

This is really bitter/yucky taste. Super easy to use, you twist the bottom and the product come up into the bristles. It’s been working so far, my child said it’s “spicy”. I just keep reminding him to stop sucking his thumbs.

But of a backstory, I bought this for my husband as well as my almost 4 year old. My husband has had a nail biting issue since he was in grade school. His nails are nonexistent and his fingers are nubs at this point. He bites his nails 24/7 and at this point doesn’t even realize he’s biting them. Our 4 year old has recently started the bad habit as well in the last year. I decided to put this on my son‘s nails at 9 AM. I am a firm believer that if I’m giving my child something like this I should also be trying it. Now I do not have a nail biting issue, but I put a dab on my hand and licked it. Holy crap this stuff taste horrendous. I instantly begin chugging water, spitting in the sink. I saw the previous reviews where they said that it made their child puke and I thought it was an exaggeration. But there I was in the sink, thinking I was gonna be sick. It is now 10 AM. The wave of bitterness and sickness passed within 2 minutes, within five minutes, I had gotten the taste out of my mouth because I was chugging water. Now an hour later I still feel it linger. I have a slight headache from the taste and my stomach hurts. It tastes almost like battery acid. It is very bitter and an absolute awful taste. My four-year-old now has it on his hands (I put it on his fingers and then I tasted it) He has yet to put his hand in his mouth. When my husband comes home will be the real test. Because I’m curious to see how long it lasts and lingers on your fingers. So as of right now, I give it five out of five stars. I will update this at the end of the week and see if we have kicked the nailbiting habit out of our house. But please be aware it is truly a horrible taste. So parents, please be aware your kid may puke.

This product is insanely effective to stop thumb sucking!! I’m in (pleasant) shock. Background - our daughter has sucked her thumb basically since birth. I actually didn’t care to have her stop yet except that the thumb sucking turned into a simultaneous hair pulling (her own hair) issue around 2.5 years old which got really bad. I bought every little hair toy, fidget item, literally everything out there to try to stop the hair pulling but nothing even touched it. I learned it is a self soothing behavior exclusively tied to thumb sucking so … our finnnnnal last ditch effort was to try to stop the thumb sucking, something I wasn’t too hopeful would work based on all I had read about how hard it is to stop with really young kids. TWO DAYS. 2. That’s it. I put this stuff on her thumbs and she completely stopped thumb sucking (and hair pulling) in TWO days. I am mind blown. Day 1/ the first time she tried it her reaction was extreme. Tears, she started drooling - it was intense. We made up a story about how when you get too old to suck your thumb it just starts to taste bad. After 2 days of applying at around 3x per day her entire oral habit seems to have stopped. She’s not even reaching up to suck her thumb or trying while falling asleep or anything!! We are now 3 weeks in and she doesn’t seem to miss it or be inclined to suck her thumb at all, even without needing the product anymore. 10/10 recommend I also tasted it. It’s awful, almost causes an oral reaction it’s so bad, but it freaking worked!!

Definitely tastes back enough for me to notice my mistake with biting nails. Dont forget then scoop food out your gums like me

Great product my daughter stop sucking her finger

Im not one to write reviews but this product is magic!!!!. My daughter is 16 months old and she developed a thumb sucking habit since she was in the womb (Ive literally caught her doing it on ultrasound) I was so worried about it affecting her teeth and becoming a long term habit that I would struggle in breaking. I used this pen before bedtime, three nights in a row, and left the residue on her thumb throughout the day. (Avoiding washing the thumb of her right hand) After that third night I decided to stop applying and see how she behaves. I am so happy to say she has not sucked her thumb not even once since then. I bought two pens and I barely used a few drops of one. But I am extremely happy with my purchase. To warn consumers though this product will get on everything your child touches. I hand fed my daughter the whole time I used this because I didn’t want her rejecting food because of its horrible bitterness.

It's easy to apply and it tastes terrible. But honestly, once it gets wet, it kind of wipes right off.. Or it's not as strong after it gets wet because my daughter goes right back to sucking her thumb I have to keep re applying. Her drool just washes it away😭

I tried this myself before applying to my toddler’s nails (a finger sucker)… and I gagged from the teensiest drop. Kid is VERY adamant on continuing the habit so I thought a little disgust here could benefit him. I applied it under the claim that “this is medicine for the owies on your fingers (from sucking them- he has blisters)”. He seemed okay for a few minutes - I thought this plan was out. Didn’t affect him. Five minutes later, he started drooling a ton and throwing up. I feel horrible… but I think maybe this will work and he is very upset about it. 😅

It did not work that good

Tastes disgusting and lasts! My little girl never put her thumb in her mouth again after only a few nights of applying the product!

حقاً منتج يستحق الشراء أطفالي الثلاثة من اول اسبوع كانت مشكلتهم قضم الاضافر محلوله والان أضافرهم جميلة

Tastes bad and dries quick and matte. Does the job.

Worked great with my 6 year old. While there is a taste, it is not over powering like others we have tried and can be washed off. Very effective and glad we tried it!
