Yup, that's her. This is at my mums 60th in July. Did you see it last night? I can't bloody find it anywhere! Though admittedly its always a bit weird seeing your little sister on the TV - I don't think I'll ever get used to it.
The documentary was an Extraordinary People episode called the tiniest girl in the world. It was part of the reason I decided to loose weight. They wanted the whole family to be involved & filend but I flat out refused due to my size. I was dodging cameras all day at her birthday party & didn't get to spend that much time with any of my nieces or sister as they were forever being put in front of the camera!
