T.H.
I was afraid of exactly the same things so here's what I did. I totally child-proofed her room: covered all outlets, covered the power strip w/ a childproof thing, installed the dresser tip preventer, locked her closet door, put her garbage and diaper pail in the closet, and I leave a few soft toys out. Then I also leave her closet light on so there's a bit of light in the room. I close her bedroom door and have a monitor in the room. She does get out of bed and play before she goes to sleep but she always ends up in her bed and when she wakes up in the morning, she'll just play with her toys until I come get her. So it worked out well. Hope this info helps! Good luck!
