Everyone loves the extra thumb, they want me to keep it and not have it removed.. But even though ideally i'd like it to be her decision, she'd go through so much bullying at school and stuff if she was different in any way.. Kids are so cruel.
Both thumbs are functional.. That's why it's so weird when she grabs your finger and 6 little fingers wrap themselves round it! The extra one is limited in how it can move though, due to its position. It's fully formed, complete with bones and a nail and everything.. It's amazing really. I don't know how common polydactyly is.. But I think it makes .Jenny special!
