Screw the shelves and furniture to the studs with L brackets. Make sure hubby cannot move them if he leans on the front. Even with the drawers open he cannot be able to move the furniture a tiny bit. Kids will climb on stuff and if it's not anchored to the wall it can flip over on them.
Make sure each and every toy, doll shoe, car, hair barrette or decoration is not a choke hazard. If it will slide through a toilet paper tube it is a choke hazard and she can choke to death on it.
Even Hot Wheels cars can be a choke hazard. They are long and narrow, they can be chewed on and when they are wet they slide very easily.
Take all the cords to any item and make sure they are behind the furniture if possible. If she has plug ins in her room get the plastic plug covers and use them in each socket. She can poke stuff into the plug and get shocked or worse.
Make sure there is nothing she can wrap around her neck, like a necklace or tie or belt sash. Kids can get these around their necks and accidentally get them too tight.
If she can get out of her room you MUST keep the bathroom doors ALL shut and secured where she cannot open them. Kids are top heavy until they are at least 3. Their neck and back muscles are just not strong enough to pull their head out of a bucket of water or the tub or the toilet. They will drown.
She can get into the kitchen drawers, under the kitchen sink, etc.....if she is able to get out of her room during the night she has free access to the house and every door knob.
So being smart about what looks like fun to her is important. If you google child care regulations then open the states child care regulations books you can look at their sections on choke hazards and safety. Many things in there are things I would have never thought about being dangerous.
