Grace sits?

For about two days now Grace has been trying to sit up. Whenever she is on an incline, like in the carseat, swing, or propped on a pillow, she does what seems like a half sit-up. She isn't quite strong enough to actually sit yet, but she's close. Ahhhhh! That means Jake will soon follow. I'm really hoping they don't walk at nine months like I did. I'm enjoying this time when they can't get into anything outside of arm's reach. They grow up too fast!
