For a while, Matty was sneaking into our bed every night and interrupting my sleep. We tried to discourage this behavior by setting up a system where if he stays in his bed all night, he gets to have a treat (usually a piece of candy). Even when Matthew wakes up in our bed and runs out of the room, though, he still tries to ask if he “stayed in his bed all night.”
And here’s a picture of the boy, below, taken this morning. No treat for him!
