No Bite Nail Polish for Kids & Adults – Vegan Bitter Taste Nail Biting & Thumb Sucking Treatment – Habit Breaker, Safe for Kids

The bitterness of this polish is intense and immediate. It is specifically designed to deter both nail biting and thumb sucking, and it works exactly as intended. The taste is very sharp and lingers, which is the perfect reminder for anyone who bites their nails subconsciously." Clean Ingredients (17-Free) "One of the best things about Ella + Mila is that it's a '17-Free' vegan formula. It’s made without harsh chemicals like Formaldehyde, Toluene, or Acetone. Knowing it’s safe and non-toxic is a huge relief, especially if you are using it on children (it's safe for ages 1+)." Application & Appearance "The application is smooth and it dries very quickly (under a minute). It leaves a subtle, healthy-looking glossy shine on the nails. It can be used on bare nails or as a top coat over your favorite colored polish. Just remember to reapply every 2-3 days to keep the bitter taste strong, as it can fade after several hand washings." The taste can transfer to finger foods (like fries or fruit), so you may need to use utensils for a while!

My 4yo was still thumb sucking at night and when he's tired. Then one night I put this on his nails when he was sleeping. The first night was rough - he woke up multiple times upset and confused about his thumb suddenly tasting bad. By day 2 he stopped fully sucking his thumb, though he did lick his thumb a few times during the day to see if the bad taste had gone away. I reapplied 2 days thereafter again while he was asleep. It has now been a full week and no more thumb sucking! He remains confused how suddenly his thumb tastes bad.... I guess I'll confess when he's older lol. There is another popular brand that sells a similar product but this one appears to be more geared towards children (at least it is marketed that way) so I chose this brand instead. The flavor of the nail polish is not horrendous but it is sufficiently bitter that it is not pleasant.

I was really hoping this would work from all the positive reviews but my 3yr old is currently asleep with her thumb in her mouth 🙃 I put it on her in the morning and when she went to suck her thumb she immediately took it out. Throughout the day it wore off from washing hands and by quiet time I looked on the camera and she was sucking her thumb again. So I applied another 2 layers and she stopped. Now it’s bedtime and she’s had a bath and she is asleep with her thumb in her mouth. I’m really disappointed that this doesn’t last very long and even after 4 layers she is still sucking her thumb. I’ll continue to put it on daily to see if it will stop over time but I had assumed this would stop it completely.

**EDITED TO ADD: came back to say, I’ve only had to reapply twice and we are still THUMB SUCKING FREE! Praise be! I never write reviews but had to share my experience as a mom of a strong willed 5.5 year old thumb sucker! We applied the polish on both thumbs on Monday before school in the hopes to stop thumb sucking at school during this horrid cold/flu season. He sucks his thumb when concentrating, when bored, when watching shows or while teacher is teaching, and to self-soothe for bed ever since we sleep trained him at 4 mo old. I completely forgot that this polish STAYS ON for a while and bedtime was going to be impacted, but there was no turning back and we needed to kick the habit once and for all, including sleep! So we committed. He allowed us to apply, and it didn’t burn or anything (“this is to help with germs and keep you healthy.”) Dried very quickly. I put it on while we were in the car and it was dry by the time we walked into school. He accidently put his thumb in his mouth a couple times out of habit that day and every time he would promptly take it out with a big YUCK! He got upset, yes, but it deterred his thumb-sucking! A swig of water solved it. We gave him some fidgets to help keep his hands busy. That night, he got PISSED and demanded I “take it off” but of course, that wasn’t an option and we rode the wave of comforting him and letting him work through it. Nights 1-3 he would get up a dozen times with every excuse in the book to avoid going to bed but eventually fell asleep! And no thumb-sucking during the days! I was SHOCKED! He even stopped sucking by accident/out of habit by the second day! Last night was night 5 and he went right to sleep! I will say I noticed after his bath on Wednesday night that the polish was starting to peel off so I reapplied it then to both thumbs, even though he had stopped sucking by then. It dried quickly again but it doesn’t last as long as they say it does, keep that in mind. I still give 5 stars because guys….IT WORKS! I’m a believer and so so thankful because I was starting to think my kid would suck his thumb until college! Every kid is different but I’m telling you….its worth a try! Hope it works for you, too! I will come back and edit my review if anything changes.

Skip this for your toddler. Three stars because this is gross! As intended to be, it leaves a bitter chemical like taste in your mouth. I think this is more appropriate for an adult who bites their nails as I would specifically be deterred from it. My 15 month old who sucks his thumb was gagging and crying, and still sucking his thumb with this taste. Furthermore, being his mom he would touch my face and hug on me and the taste would be in MY MOUTh and was unpleasant. I think it bothered me more than my son LOL. There are some gloves I ordered here they are white mesh gloves that fasten with a string. They work really well for a small child. As long as the gloves are on they forget about their thumb, recommend that over this polish- just skip it. Hope this helps

Wow. Super effective and strong bitter taste lasts forever! I put some on my pinky before applying to my toddler's preferred thumb for sucking. I was shocked by the strong taste. I wish I tested it out a few days to a week before I applied to her thumb because I didn't realize that I couldn't remove it easily. I wanted it to last through school, but not at night when she may need to self soothe. In short - not a great temporary option But amazing long term.

Wow! This works perfectly for my 3year old baby who has been sucking her thumbs for about a year. I tried so many things and nothing worked, until I bought this! I applied it one night after shower, before bed. She was hating the taste of her thumb, she was spitting out with disgust. That’s was all it took, ONE night! She has never tried to suck her thumbs no more!!! Although,when she was tasting the disgust I was telling her “don’t suck your thumb, they taste horrible “ she cry for a bit until she fall asleep and NO MORE! It’s a win for me.

Received 4/23/2026. Applies smoothly and dries fast. Tastes really bad. I am hopeful this will work. I will give an update in a few weeks and I’m am a long time nail biter😩🤣

My twins love to suck their thumb. It’s a habit. Tried all but no avail until we found this product. After every shower have to reapply to ensure it’ll work. Done for 7 days and now the thumb habit is non existence. Thank you!!

Me encanta! Después de larga búsqueda le. Ayudado a mi hija para no morderse, lo usa constantemente ya que con las lavadas de manos se va quitando.

No funcionó, mi esposa siguió comiéndose las uñas aun con el producto en los dedos.
