Sadie's Mommy Sensor went off. I was doing something that didn't involve paying attention to her (completely at least). She went for the book. I closed the book and put it on the top of the table. Sadie spent the next five minutes using all her energy climbing her way up the three levels of the table into a standing position, while I spotted for her, in case she lost her balance on one of the magazine pages she'd shredded that I hadn't yet had a chance to pick up.
Once she was sure that I wasn't doing anything other than paying attention to her, she sat back down (with a little help) and started to crawl across the room. After making a loop of the room she headed back into the living room (with me trailing behind).
I was surprised when she turned right, because she has rooms that she has explored and the den and bathroom aren't on the list. Instead she stopped in the middle of the hallway and, after failing to pull several books off of a book shelf, stood up, held onto the third shelf and pulled a glass bottle filled with agates off of it. I caught it just as she let go (and looked disappointed that it didn't hit the ground).
Now that she's pretty sturdy on her feet (although she didn't walk on her own today) there's a whole other level of baby proofing that is going to have to occur. She's very determined when she wants something and she isn't deterred when I hide things from her. She watches me and then she tries to work to get what ever it is that I've put out of her reach. I can't believe how fast she's growing!
