Bow-legged monkey walk?

TheBub

DS is slightly bow-legged and walks with his belly sticking out.  I thought this was normal until recently when people have been commenting on it frequently...and not in an "oh look how cute that is" way.  We have his 15 month appointment next week, but I wanted to see what you guys think too.

M still runs like that and it's especially funny when she's swinging her arms over her head. M's pedi said it was totally normal.
