D.Q.
Maybe I'm in the minority, but if your dentist isn't concerned and there are no medical issues, what's wrong with a pacifier? Besides what other people think, what does your gut tell you? My 8-year-old had one at night until he was 3 1/2 (I know some of you are just shaking your heads right now) and his dentist never believed me when I told him he used one. He is now a very bright, totally well-adjusted 8-year-old who brings me joy every minute...even if he did have a "dat-dat" longer than his grandmothers would have liked.
