All my kids have had Dummy's and Jack still has one, my older 2 both got rid of them a bit after 2 and a half. We said that they had to go to the other babies, but them in an envelope and then (we didn't of course) mailed them.

I am totally with you on not liking her having it in her mouth when she is older. I just became really strict from about this age onwards about it being for bedtime only. I had a special box and when they woke up the dummy would go in the box that was on a shelf and then wouldn't get taken out again til they were in bed. If my eldest would want it during the day (not sleep time) I would say to him that he had to get into bed, which he didn't want so he soon forgot about it.

I think it did help for my boys being older when I took it off them because they understood what was happening.
