Somewhere between Thanksgiving and Christmas, you learned to sit up by tri-podding with your hands. You could sit up but not do much because if you moved one hand, you would tip over sideways or (more impressively for us not-as-flexible older folk) fold in half. The day or so after Christmas, you started being able to stay up without your hands, very wobbly with frequent tips and resets at first, then for longer and longer on your own. You think this is awesome and give anyone in a room a smile and a statement of excitement. Reaching for and holding toys while sitting is still a bit much to handle. Just think what you’ll be able to do in a couple more weeks (Mommy and Daddy are picturing objects being thrown from a high chair…).
