Kids away at camp

Our older 2 children are away at church camp this week and boy is it quiet. No fighting or arguing or trying to stay up later than us. We only have the one at home to spoil and boy is he getting spoiled. Every night so far he has gotten up at 3:00 am and crawled in bed with us. I know we shouldn’t let him but he’s still my baby (7yrs old) and gets scared in this big house in a room all by himself.
