This is so hilarious. My own daughters did something similar around the same ages. The way I found out was the older one (maybe 3?) came in with her hands behind her back and asked, "Mama, um, does hair grow back?" This question struck fear in my heart -- especially when I saw the locks of blonde hair clutched in her little fists. She had cut her 2-year old sister's hair "to the quick" -- she was actually completely bald in spots. How she didn't draw blood I'll never know! How I wish I had thought to "interview" them about it -- You'll treasure this adorable clip forever. Thanks for sharing.
