Query: Does not work the way it is said

I bought this item for my two daughters, one two and half and other one ........both were annoyed when i used first time on thier thumbs but after that it did not make any difference to both of them, i was disappointed that how can this could be...... now i think there is no other thing which could stop them from thumb sucking.People have given very good reviews about this ....that's the reason i had purchased .......it was not at all helpful for our case.
