Did you know that a mother can instinctively identify her child's cry out of a crowd? It's a trait that came in handy when we lived in villages with many little ones running around. If a woman woke every time she heard a baby whimper, she'd never get sleep. Instead, a woman's brain only signals to wake her if it is her baby doing the crying. And studies have shown that even though it is no longer a necessary trait to have in most developed countries, mother's haven't lost that gift. Fascinating!
