Since the conversation has moved from windows to lofted beds, in 16 years out of a crib at home, how often has your child accidentally rolled out of his/her standard-height bed at night? As humans, we often feel that the higher up we are, there is some extra gravity pulling us down, but that’s just fear at work. A human being who has successfully slept in a bed for 16+ years is unlikely to start falling out (even if it is on the edge of the grand canyon, with no fence!)
