This morning, Oliver was hanging on to his changing table shelf and grabbed a book off of it, as usual. Then, something different happened. He let go of the shelf to hold the book in both hands, and he wasn't leaning against the shelf. I was right next to him and in complete shock. I didn't want to startle him, so I just sat, watching. It only lasted about three seconds (at which point, he toppled, and I caught him), but it was amazing!
