Jonathan learned to sit up today. Yesterday he couldn't do it without help, and today he can.
It is so satisfying to see him do something that I've been working on teaching him. We've been actively practicing the whole sitting up idea for the past week...and now he can do it! I suppose he would have learned it on his own eventually, but I do feel a sense of accomplishment in his new skill.
It helps me see the value in sitting on the floor for hours playing with him. Because playing is his work, and practicing things like sitting up and rolling over and holding his head and torso up when he's on his tummy are all important skills that he wouldn't learn (or at least not in the same way) if I wasn't there working with him.
And I love it that I get to be the one to discover his new talents. Not a babysitter, not a day care worker, but ME. :)
