Sit Up and Take Notice

With a little help from mom's nursing pillow, Jonas sat up all on his own today -- just a week after an unnamed family member mocked him for his inability to sit without the aid of a chair (I believe the comment was, "I'd be envious of his chair, too, but I can sit upright"). So take heed, all those who doubt Jonas.
He has abs of steel and an iron will.

(If you look close, you'll notice some projectile spit up just before he makes his move; you can't swim on a full stomach, and if you're a baby, you can't sit up on one either).
