From the 5yo - almost 6 yo; he just informed me this morning, "3 more days" - last night after he went to bed, he got up .... he yelled this down to us from the top of the stairs:
JP: "Daddy...[ mumble mumble mumble]"
Paul: "What John Paul?"
JP: [with a whiny-on-the-verge-of-crying-tone] "I can't get to sleep up here. I'm dying of starvation!
And yes, we did rectify this problem of starvation with a fruit bar AND a threat of "don't you dare tell Joseph" - with whom he shares a room :)
