My baby can crawl now. She was working her way up to it for weeks, often backing herself under furniture and yelling for help to get out. She's more content now that she is mobile enough to reach much of what she wants to touch and/or mouth. I love her wide, toothless smiles. :)
I always put her to bed in her crib, but sometime during the night she cries, and then she often ends up with me in bed for the rest of the night. If I leave my bedroom in the morning before she's awake, I have to keep an ear out for her because if she wakes up and lies on the bed too long without being fetched, she can move herself off the bed. It's not super high off the ground, but it's still best to avoid a fall. If you haven't been around a newly mobile baby recently, there's a distinctive "thump-waughh!!" sound they make whenever they fall.
