My son has been sucking his thumb since he was in the womb (could see him doing it on the ultrasound!). Though it made him a great sleeper as a baby, now at 5 1/2 it was time to stop. Now he's losing his first tooth, the dentist told him he should stop too. Fortunately, my son is very taste sensitive, so he really did not want to suck w/ the Mavala on. Unfortunately, the first night he woke up screaming at 2am because he sucked and we had to deal w/ the rinsing and wiping his tongue off w/ a towel! He kicked his habit within 2 days, has not sucked in 4 weeks now! (BTW, we started putting a sock over his hand so he would not accidently suck at night time)

I have been biting my nails for as long as I can remember, and it seems like I have tried everything out there to help me quit-this product is the only thing that worked for me. I put it on my nails every 3 days or so. The taste is horrible, and lingers in your mouth for a while-it really discourages you from putting your fingers in your mouth. I recommend it to anyone who needs to stop biting their nails.

We bought this for our 4 year old daughter. She had been biting her nails and sucking the thumb for over an year. We had tried "Thumb Liquid" and puts tapes on her fingers, but it not work. The first day we covered the thumb and fingers nails with the solution. She hated it and was vomiting. We then removed it with the nail polish remover at night. The next morning we just put a drop instead of covering the entire nail. We would put this in the day and remove it in the night for the first 3-4 days. After that we would let it stay. It would last for couple of days. Now after couple of weeks, she has stopped biting our sucking the thumb. She would bring it near to her mouth and then stop there. I believe she will stop doing in another couple of weeks.

This was so very easy to put on my daughter's thumb to get her to stop sucking it. She is 5 and has been sucking for a very long time. The dentist was recommending all these contraptions to put on her thumb but they were all so expensive. When we found this one, I was like, what could it hurt to try it. WE have only had to put it on maybe 3 times and she hasn't sucked her thumb anymore!!! It really works!! I even used it on myself and was able to stop biting my nails. It is an awesome product that is small enough to fit until your purse and go anywhere, is always there when you need it.

Yes this will keep you from chewing your nails, it will also ruin a lot of other things. I was using this to keep my son from chewing clothing, and other things. While I had it I thought I would try it because I chew my nails a bit. Then I found anything I touched and trying to make dinner was impossible. Everything tasted like this stuff, had to stop using it.

Our 6-year-old daughter just couldn't seem to shake her awful thumb-sucking habit, until we found this product. After just a week and a half, she has completely stopped sucking her thumb. We didn't even make it to the three-week mark, as we didn't need to. Now, about 1 month later, she has shown no signs of thumb sucking again. Thank goodness. My only recommendation is to use it in small quantities on the offending digit, as we originally put excess amounts on all of her fingers and then she complained about eating, etc., as mentioned by another poster above. Once we dialed back the dosage to just the target thumb and only applied a small amount near the tip, all seemed to work well for us. We highly recommend this product.
