OX's latest project is rolling over from his back to his belly. I let him have at it last night on our bed. He made all kinds of loud noises - yelps, squeals and grunts. He's almost got it; he just needs to get that one arm out of his way. And, when he does get close, he seems angry that his body betrayed him and flipped him over without his permission.
In other news, Zee went on her first field trip yesterday to the Shedd Aquarium. I had no feedback other than she was in a great mood when I went to pick them up. She likes these excursions, and on Saturday we may go to one of the children's museums or the nature museum in Lincoln Park for some mommy and Zee time.
