Hey Michelle, just looked at the pics SO CUTE.
My Lily did a similar thing when she was two and again when she was three. The first time she found Grandma's scissors and cut off her whole pigtail, elastic and all. Keep in mind that I cultured this child's hair from the day she was born and it was well below her shoulder blades. Her grandma took her to the hairdressers, where they tried to mask it with a comb over. When I saw her I cried. I had to take her back and ask them to cut it short short. She looked like a little pixie.
The second time I left her in the care of DH while I picked up the twins from a birthday party. Her fringe was long but I hadn't gotten around to getting it trimmed. When I got home she had chopped the WHOLE fringe completely off. More tears shed by me and a big scream at DH, lots of beanies that Winter...until one day, I tried to put a hat over the stubble and she ripped it off me, looked me straight in the eye and exclaimed ..."It's MY bolt (bald) hair, and I LOVE it"! Needless to say we have hidden all scissors from her since!
