My DD is a furious fist sucker which i pressume will progress into thumb sucking. I have tried to give her a dummy, but she is just not interested at all.
I had the same dilema. She has never been upset enough to give her a dummy for comfort but i thought i would give her a dummy to head the thumb sucking off......... no suck luck, so hopefully she'll grow out of all the sucking before her big teeth come!
