My 3 1/2 year old cut her fringe off last week. We'd trinmed her fringe the week before, but she thought it still wasn't short enough. I got home from work, said hello to DH, and then looked at Isobel. DH looked as well, and all she said was 'gone'. DH hadn't even realised that she'd done it! LMAO!
She has totally cut the fringe off next to the hairline, but hasn't touched the sides or back, and thankfully left the 2 year old alone.
