we have a thumbsucker here and I LOVE IT. it never falls on the floor, I cant loose it and it doesnt need replacing.
Jordan only sucks his thumb when he is tired and to fall asleep. We tried the dummy however he spits it out and replaces it with his thumb so I figure he doesnt like it.
I am sure he will wean off the thumb when he is ready. I dont have the heart to pull it away from him.
