I had two who were determined to suck there thumb. I gave them the same blanket every time. Eventually they learned to associate the blanket with thumb sucking. When it was time to break the habit I just found a new blanket and sent the old one to the "repair" shop. Within a month they were done thumb sucking and the old blanket returned. But the habit was gone. It did this just before age 2. It worked very well with both my boys.
