Does he sleep if someone is in the room with him? My son hates sleeping alone. He says it is unnatural for a defenseless young social mammal to sleep away from its herd in the dark and that asking him to do so violates his instincts.
He sleeps much better with his brother and/or the dog.
I love your son's argument! And he's also backed up by the co-sleeping practices of most humans on the planet throughout history. The expectation of separate sleeping quarters for juvenile humans is pretty much an artificial practice specific to members of industrialized first-world cultures with the luxury of more space than people (and not even all of those do it).
