Hoof Stop the Bite is an anti-nail biting polish that tastes very bitter, and as a result discourages nail biting for children 4 and older. The manufacturer and some marketers also claim that it prevents thumb sucking, however we do not agree.

It intended to help stop finger nail biting in people who are motivated to stop, however the success rate of thumbsuckers is extremely low. For people who subconsciously put their fingers or thumbs in their mouth it is an excellent reminder to stop nail biting or thumbsucking. If you are looking for a solution to stop adult thumb sucking during waking hours or you simply need a reminder and who really wants to stop fingernail biting, then any anti-nail biting polish is a good choice for you. There are several choices including lower cost options.

While it seems natural that Hoof Stop the bite (or any other anti nail biting polish) would also work to stop thumb sucking, it does not. First, it is important to understand how the polish really works – it tastes bad. Is it so bad that your child will absolutely not put their thumb or fingers in their mouth? Well.. no. It comes down to what is worse, not sucking or enduring a bad taste. For serious suckers, you need something that will physically prevent the thumb from being sucked on.

Although Hoof Stop the Bite usually does not work on its own, when used along with a physical device – one that obstructs the thumb from the mouth – it can be extremely effective. Especially when the device is taken off, the bitter taste will continue to stay on as a reminder. We recommend the nail biting polish be used in conjunction with any product that physically obstructs the thumb sucking.

Many children will actually get used to the taste in about a day, rendering the product totally useless for them. Your child will definitely find the bitter taste disgusting at first, but a stubborn child will quickly get past it. Think of your first sip of coffee.. it was probably gross, but then, you learned to like the bitter stuff. Hoof Stop the Bite is the same kind of thing.

For stubborn children, or people who have a psychological dependence on sucking their thumb, the bad bitter taste is not a sufficient deterrent. And for the night-time thumbsucker any anti-nail biting polish absolutely won’t work. Many children go to bed without sucking their thumb, but start to in the middle of the night (this is perfectly natural until the habit is stopped), and they do it while sleeping. Their taste buds are not sending the “yuk” signal to their brain while sleeping. When your child sucks their thumb while sleeping it’s automatic, they don’t know they are doing it. So basically it is involuntarily and when they wake up there is this disgusting left over mouth taste and it is like punishment for an undeserving crime.

Common questions asked about Hoof Stop the Bite nail biting polish for thumb sucking include, is it effective at stopping thumb sucking, and what are Hoof Stop the Bite ingredients.

Is the nail biting polish effective at stopping thumb sucking? By itself, probably not. The reason is simple. Children are more driven by the comfort of having their thumb in their mouth than they de-motivated by the bitter taste, and, the taste has no effect at night time while they are sleeping. Of course, everyone will experience different results. It does work extremely well for some, but results vary and most are not successful, especially with stubborn kids.

Because you are concerned for the safety of our children, we want to know the Hoof Stop the Bite ingredients. Since the product is technically a nail polish it is not intended to be ingested, the FDA has not reviewed it. However, its competitor, Mavala Stop claims that its polish is harmless, and since thousands of people have used it we assume the ingredients are similar and indeed harmless (but do your own research!). And although the ingredients looks less intimidating that those on the back of a Twinkie, they are certainly not all-natural. Mavala Stop ingredientsThe Mavala Stop ingredients include Ethyl Acetate, Alcohol Denat., Butyl Ester of PVM/MA Copolymer, Phthalic Anhydride/Trimellitic Anhydride/Glycols Copolymer, Butyle Acetate, Acetyl Tributyl Citrate, Sucrose Octaaacetate, Denatonium Benzoate, Isopropyl Alcohol, Benzophenone-1, CI 60725 (D&C Violet No. 2).

Hoof Stop the Bite should not be used for infants because Alcohol Denatured is made of 95% ethyl alcohol and 5% methyl alcohol in USA. Methyl alcohol is a poisonous chemical, and for infants whose immune systems are undeveloped even tiny amounts can have adverse effects.

Hoof Stop the Bite retailers are plentiful. The best price will be online of course. You likely won’t find it at your local CVS or Walgreen or Walmart because it is the most expensive nail biting polish available, so the best place to purchase the product is from an online retailer such as thumbs down
