Hi, M. -
All three of my children had their "duppies" until they were three, and then (pardon the pun) I pulled the plug. Up until that age, I think they are still babies and need the comfort. After that, it just ruins their teeth and isn't socially acceptable, and I did worry that every day that passed would just make it harder. You know what? At three, you can explain that they are big boys or girls now and don't need it any longer, and then you just take it away. I absolutely expected the worst, and it just wasn't that bad. We had one or two nights of difficulty getting them to sleep, but after that it was simply over and done. Not the drama I expected, and my kids were addicts. Each one of them wanted one pacifier in their mouth and one or two in their hands, would have them every minute they could get them. They would put it down, take a bite of food or sip of drink, then replace it. Anyway, my point is that if kids addicted as badly as mine were can kick it in a couple of days, I think most kids could.
Good luck!
