Breaking Habits

My first daughter never wanted a binky, never sucked her thumb, and never carried around a blanket. Oh, how easy I had it.  My second child wanted the binky, loved the binky!  At 18 months she gave it up cold turkey. Yahoo I thought, that was easy. Well, she then found her thumb. What would I do now? I can't throw out her thumb..can I? No, no, just kidding.  So, what did I do? Not much honestly. I encouraged her to keep her thumb out of her mouth and a few years later it has nearly worked.  Here and there I still catch her with her thumb in her mouth when she is really tired. So, here it is in print (or type I guess), I have no words of wisdom on this topic. If you do, please share your thoughts. Lets get a good Mammasori conversation going.
