The next day, I experimented with the end of the pacifier. So far it has been a week or two, and we haven't back slid.
So I think I'm ready to say, we're done with the pacifier. One less thing to keep track of. One less thing to wonder about how/when we're going to end it.
I hate to say it, because I don't want to jinx anything, but it was remarkably easy. One day, at naptime, I just told her we weren't going to use it anymore because it is bad for her teeth. She asked for it at bedtime and naptime for several days, but wasn't upset when I said no.
Huh. Not every parenting issue is a teeth pulling challenge. Go figure. I'll have to keep that in mind the next time I want to quit.
