Sofia has several fetishes (Is that how you say it?). Anyway, she loves shoes...in particular shoes too big for her. Usually it's my high heels, but she also likes to wear anything that is Hannah's. She also really likes socks....used as mittens. Here's a picture to show:
When she was still a small infant we had lost all of the baby mittens (or maybe I just didn't keep any since Hannah never wore them). Anyway, to improvise, I always took a pair of socks and stuck them on her hands to keep her warm. Maybe that's the cause of it?!
