Dylan is turning one on Wednesday, and he just got his first tooth a couple of weeks ago. His second tooth came in the very next week, but that's it so far. Both of his teeth are just barely poking out.
I wouldn't be too worried about it, if I were you. My pediatrician said that the range of dates for the first tooth is pretty wide, but he joked that we could always have Dylan fitted for dentures.
My friend's daughter didn't have a single tooth until she was 17 or 18 months old.
