DD1 (2.9) has sucked her thumb since she was 4 months old. She only does it when tired or upset, but I (and the dentist) think it's time for her to stop 
So, anyone got any tips? We've explained it will stop her teeth being pretty, but when she's tired she doesn't care!
I remember reading a thread on here about 2 years ago which mentioned a book (Thumbuddy to Love ) but it looks like it's out of print & is very expensive second hand!
DD2 (3 months) found her thumb yesterday so any tips to stop her also appreciated! (she won't take a dummy)
