Hello - My 7 month old daughter also sucks her fingers...but her middle and ring fingers! ((it looks like she is holding up the "i love you" sign)) and while she sucks them, she takes her free hand and rubs a blanky on the hand in her mouth...she has been doing this since she was about 2 months, and she never took a binkie, which i think is good...i'd rather have her suck her fingers than a binkie...but my advice is to keep trying a pacifier in place of her fingers, and keep using the glove...i think she will eventually suck the fingers on the other hand if she wants them that bad...best of luck!!
