Last night I popped in to Walmart and Home Depot on the way home and bought some outlet covers, childproof plug covers, and some flat ended extension cords. I fixed the one cover behind D3's bed and put plug covers on the outlets except one - which I plugged in the extension cord for a light and his clock.
I finished emptying the books out of the first bookcase. Even though he said he didn't need one, we moved that bookcase into the corner of his room. It was a tight fit but it's there. He actually slept down in his room for the first time last night.
Now I can begin the slide-puzzle moves to get the rest of the family room usable again. I have to move the TV where the bookcase was and move the toy cupboard so I can put my desk in that corner. I can move the bed and pile games on my desk so I can move the game shelves where the bed was and then put the bed where the game shelves were.
Then we can work at emptying another bookcase and moving them down so we can put the toy cupboard on the bookcase wall. That may take a bit longer.
