Hi. I wouldnt worry about it too much..especially if its just for sleep. My son is 2 and we got rid of his in september. We kept telling him that the "pinky fairy" will come and get it when he no longer needs it and give it to a baby who does. We talked about it for months until he would start talking about the "fairy"...and one day...it disappeared...he would ask about it but we would just say that the binky fairy took it. He now sleeps fine..actually better than with it. Hope this helps alittle. You need to try different things. Now we are trying with diapers..that should be interesting. good luck!!
