I have long since forgotten where I heard this phrase—it may have been Zig Ziglar—but, “fight for the bottom”, has been used in our family for years and is now being quoted by my grandchildren. It has diffused many arguments in our household, and it has the capacity to do that for yours as well.
When a child is born, he knows nothing other than himself. He has very few needs—to be fed, changed, or put to sleep—but those needs are immediate, and they become the central focus of a household. Babies don’t know how to wait. And the only way they know to make their needs known is by crying.
