It is tough to have house full of sick kids with an absent DH. My youngest decided at about 2 that he didn't want to sleep in his room so we got him a turtle that lights stars onto his bedroom ceiling (similar to a dream light) and we got him a moon in my room. We told him that if he stayed in bed that we would keep the turtle and the moon in his room. It seemed to work really well. Plus you can't see the stars very well if the room is light so he actually liked the room really dark. A friend of ours had the same problem with their girl so they got her a beta fish for her room and told her that the fish would be lonely if she left it in the room by itself at night... apparently that worked too:)
I didn't get my BFP until 11 DPO and it was sooooooo faint at 11 DPO that I thought I was seeing things. I ended up posting it on Count down to pregnancy so I could use their invert tools to see the pos. That website was actually very helpful. Here are my pictures and you can play with the "tools":
