LOL, my beautiful son Charlie has bore weight on his legs since birth and he is now 18 months old...whenever he had the chance he would stand on his legs, and it made it really easy to wind him! He is now walking/running/climbing and not a bandy leg in sight.......

Newborns are supposed to have a "walking" reflex, which most grown out of by 6 weeks and should return by around 9 months. (Or in my sons case they it never goes away ever). Looks like your daughter is the same. My paed said it was nothing at all to worry about.........
