I have read somewhere that most kids wean themselves at about 6yo.
My BIL was a thumb sucker and aparently he still does it when he has too much to drink.
Violet has started to be a thumb sucker so I try not to let her have it, I use the dummy instead... I think I have nearly beaten it, she just chews on it now.

I think the reason I don't want her to suck her thumb is because I know how hard these habit s are to break. I used to rock myself to sleep and did it for many years... and I was very embarrased about it. So I think in the long run it will be easier to take the dummy off her than try to get her not to suck her thumb.

Sorry that didn't help much, just wanted to add my little bit 8-[
