Go to bed

Superman just graduated to a big boy bed. There is only one problem with it. He wont stay in his bed. Every night we lay him down kiss him and tell him to go to sleep. We leave the room and all is quiet. Any parent knows that when everything is quiet that usually means that the kids are asleep, but to our surprise he is not sleeping he is missing. He leaves his bed and goes hiding behind the couch, in sisters room under laundry, in the toy box, the list goes on. I am amazed that a 18 month old baby can be so quiet. I am hoping he overcomes this desire to hide. It is wearing me out.
