I wouldn't stress Bec,
you know the most stable shape is a triangle, and with her feet in this position she probably feels most stable.

Violet holds her feet like it a bit too, and her toes curled under. I think once she starts walking and it is a pronounced action, maybe see a podiatrist (before 2yo as the bones are still soft enough to fix). If it is something that continues it may be something thay can fix with time.
