Worked when nail polish couldn’t.
After trying the nail polish on my seven year old for a week I was about to give up. Amazon recommends mavala stop very high for thumb sucking but it did not work at all. My son got used to the taste in just a couple days and it didn’t bother him at all when sleeping. I liked the nipit because the fingers are kept free, and after one week we noticed a big change in the habit! Hugely happy! Recommendation: follow the plan, and give lots of positive encouragement to your little one.
