These seems like a silly post to put in milestones. DD started walking backwards tonight, and like all new things had to do nothing but walk backward all evening until bedtime!
She was cautious and seemed to sense when she was going to run into something, but giggled through all of it, what a goof!
She is almost 13m and began walking 2.5m ago, and her going backwards was something I had never thought of (nor did I ever think she'd think it was awesome!) as something I would notice.
Did you notice when you LO figured out going in reverse?
