Don't leave the doors open or she will go explore. As a matter of fact, when I see her heading down toward Ryan's room, I usually go to check if his door is closed. She pauses to look at me, then quickly turns and takes off! She can crawl super fast when she's on a mission!
And that applies to the refrigerator door, too.
She knows where her stuff is. And she knows what she wants...the top on this bottle broke when she knocked it out, and so she was then able to get it off and drink away!
