No one's in there

The girls cleaned our one of their tubs of toys and just think it is the funnest game to stick eachother in there and drag it around the house. (So far it's holding together better than a cardboard box) I've taken off one side of the handle so there is no way to lock it on there. They think they are fooling me when they bring me the tub and say 'mom no one is in the box'.
All my kids are snugglers which I love after 8am. :) The rule is they can't come in our bed until it is light outside and that has cut down tremendously on the 4am sneaking in bed with us. The is pretty much the morning routine of waking up. Darian somehow comes in exactly as the sun is coming up, sneaks in the bed and falls back asleep for another 30 or so minutes.
