successfully on 2 daughters ages 3 & 6. It was recommended to her by a dentist. From the reading I just did on the product, it goes on similar to clear nail polish and doesn't wash off. It has a bitter taste that deters thumb sucking. The reviews are mostly positive. Let me know how it works if you try it!Four out of my five have sucked their thumbs and two have stopped around age 3. I have always connected thumb sucking with a favorite blanket so that when they grow out of needing their blankie, they have stopped sucking their thumbs. This has also helped to make it a bedtime only habit since they don't carry their blankies around with them. I'll let you know if it works with the other two!
If you have any other ideas, please comment on this post.
Good Luck!!
