Thanks girls!
They clip in, they're really easy to put in and take out. I'm gunna wear them for nights out and on stage mainly, but I'm just testing them out today.
Just got back from the appointment. We waited an hour and a half before we were seen.. Luckily .Jenny was in a good mood and stayed asleep for most of the time. The doctor said he'd prefer to wait til she's 1 to do the operation because she'll need a general anaesthetic.. but it'll only be a day in hospital, which is good.
He said because the extra thumb isn't a hereditory thing, it was just a random occurrence and my future children are unlikely to have an extra fingers or toes. He showed me how they were going to remove it, and I'm confident he'll do a good job. I just don't want my baby to be in pain
