I recently met two sweet sisters who sincerely wanted to stop sucking their thumbs (actually it was their fingers rather than thumb that they constantly had in their mouths). The girls were wearing braces but still could not stop the behavior.
Their single mother was also highly motivated to have the girls stop sucking their thumgs since she was the one who had to pay for their braces.
I told the single mother about Heart-Centered Hypnotherapy and how it works. I told her I could help the girls eliminate thumb suck behavior.
Steps to eliminate thumb sucking behavior:
Mom was elated with the results. She reported two weeks later, sending pictures of the girls, “Hi Diane - Just wanted to drop you a quick hello and let you know that so far there have been no fingers in the mouth since we came back from vacation and they have not even needed to go back to the recording. You are fantastic!!!”
These NLP techniques work exceedingly well with children (collapsing anchors, anchoring a resource state, and rehearsing a desired future self).
