How the Bean came into Being

How did Charity's nickname really evolve into Bean?  They have no immediate relation or obvious connection.  So let me explain.  No, there is too much.  Let me sum up.  When Charity was little, about a year or so old, we, the entire family would call her Charitina Bina.  Then it turned into Charity Bean, and then ChariBeanie.  Gradually, syllables kept disappearing and we had Charibean, Beanie and Beanie Baby.  Then, obviously, it evolved into just Bean.  Other incarnations of the Famous Bean Murdock:  ChaBean, Bean the Wean, Beanie Weanie, Beanie the baby, Cherry (which actually is not an incarnation of Bean-just in case you were wondering), and LaBean! I'm sure there are others, but I can't recall them all.  Her nickname was an acquired taste for her.  But for us, and no matter how much she fussed, whined,  complained, told us not to call her that in public, or tried to hide it, it became an evolving term of endearment that she will never be able to outgrow or make us forget, even if we wanted to. It's too ingrained. And it's tangled up in too much affection.  The Name of Bean is said with great love.
