When T. was first walking, he liked to carry around a bowl with a ball in it (or some similar container with object in container). I figured it was just a challenge he set himself: can I walk _and_ carry something around? Now A. is doing the same thing. Her choice of object to carry is a little different (she's carrying around a soft bag with soft balls in it) -- but not very different. And sometimes she carries something in each hand. Toddler projects. Gotta love 'em.
