I sucked my thumb until I was in the 4th grade. I finally stopped when I accidently started sucking during a evening movie at school. I was so scared that someone in my class saw me but no one did. I didnt want it to happen again so I stopped. However I do know someone who still sucks their finger (instead of thumb) and that person is in their 20's, its a coping thing. DOing it when they want comfort and dont know how to deal with what they are feeling.
I had a calus as well on my thumb and a little overbite because of it. If your DD doesnt stop on her own I would talk to her doctor about how to help her stop and to deal with the comfort issues. But thats just my two cents.
