The baby is rarely alone here. Most of these rooms are shared: small beds side by side for the older ones, a crib or a bassinet for the youngest, and a grown-up close by with a baby in her arms. The pets had the same idea, and more than once a puppy or a kitten is asleep in the crib while the blocks and the stacking rings stay where they were dropped on the floor.
Open a night one last: everybody is asleep and only the moon lamp is still on.
