Yesterday as Babs was trying to play with the Boy, she said "Babies do's what they want to do." I agreed with her. It's true, we can't make him do much of anything, and he certainly doesn't respond when we say "no" or "don't do that" or even "come here." I believe Babs was a little wistful in her comment, wishing she didn't have to comply either.
But as I thought about it later that day, I realized that there is plenty he doesn't get to do, even when he wants. He can't move much of anywhere unless I move him. He can only protest when things don't go his way, not actively change them. He is still figuring out how to even move his body.
So they do what they want, but only within their abilities. Now if I could only explain that to her.
