When my third son was born, I ended up putting my second son to sleep at night. He would crash on the top bunk while the older son slept on the bottom. The two of us would climb up there, and I would come up with some kind of silly song or a story or two to help them shut their eyes and drift off to sleep. More often than not, it seemed to work. One of the stories I recall was about extraterrestrials that were oceanic, terrestrial beings, also known as OTB.
