Thumb Sucking 4 year old.
I have tried a lot of different product to stop my daughter from thumb sucking. Other products helped temporarily, but she eventually found her way back to the habit. This polish the worst tasting yet. She hates the taste and has not put her fingers in her mouth since we started using it. She used the sticker chart to count the days and she has not sucked for weeks now. We stopped using the product after 3 weeks, happy with the results!
