I have a 5 month old little girl. She has always sucked on the 2 middle fingers of her left hand. She wont take a pacifier, we tried. We also tried putting mittens and socks on her hands to keep her from getting to her hands. She somehow managed to get them off. We tried a product called Thumb. It didnt phase her any. She kept right on sucking. Now she has huge blisters inbetween her fingers. They are starting to spread to the cracks between her palms and fingers. Has anyone else had this with their babies?
