DD is 17 months and a real live wire. Her latest thing is standing on her head (feet on ground, bum in air and looking through her legs), which I'm sure all babies do at some point, but I can't help but cringe at the thought of her breaking her neck! It just goes through me when she does it. She likes to rock in that position too and has almost gone over a couple of times. Am I being totally paranoid or should I try to discourage it somehow? (Yeah, like I'd be able to...)
