Hi L.! My son, also named Joshua, will be 12 months old on July 10. I am also wondering when is a good time to ween him from the pacifier. The only time he really takes it now is when he is trying to go to sleep or when he wakes in the night. We got to that point because I just kindof didn't let him see it during the day. Out of sight, out of mind, you know? It took a little while and I did give in a few times when he was really fussy, but it is working. I am not going to completely ween him until he slows down on his teething. I just think that he kindof needs something to help comfort him during those painful, miserable moments. As for the teeth, have you asked your daughter's pediatrician or her dentist? That is definately on my list of questions for the 1-year well baby visit. As for my son, he has 4 teeth on top and 3 on the bottom, with one more trying to make it's debut on the bottom. I have heard that some babies will give up the pacifier on their own time, but I hope that whatever you decide to do works for you and your daughter. Good luck!
