My DS1 was 2 1/2 when he finally gave it up! I was so worried we'd never get rid of it. He unfortunately had a fall and injured his mouth and teeth badly and didn't want his dummy because it hurt so I hid them and that was the end of that LOL!

I have heard of others who have "given" their dummies to the Easter Bunny, Santa, etc. overnight and received a present the next day . I will be trying this with DS2
