Avery is 6 months now and is on real food AND working on crawling. I'm not pushing her but it is daddy's favorite nightly pasttime to "coach" her on building her upper arm strength and getting her knees under her. Right now she's mostly in "plank' or "push up" position then puts one knee down, whines and puts it back up, then puts the other knee down. Lots of bobbing. She's trying but usually ends up scooting back away from her desired toy destination.
And she's also started real foods. You name it, she's tried it and LOVES it! Well, most of the time. But she thinks it is lots of fun to bang on her tray, blow raspberries with a mouth full of food and sit at the table like a big girl.
