Seems simple enough, right. I know that biologically I am a mother. But emotionally, spiritually, intellectually...I am not so sure I have achieved the status.
I just finished reading a book called Extremely Loud, and Incredibly Close. Though it isn't a book about a parenting model, it did have some thought provoking ideas about life and parenting. In the book, a man keeps a catalog of people that he deems biographically significant; however, he defines everyone he puts inside with just one word. And that got me to thinking... If I boil myself down to my most concentrated part, what one word would I use to define me?
These past three months have really been an intense time of altering my definition of myself. Before now, I saw myself as many different things, wearing many different hats, some vastly more important to me than others. Here is a brief study of my previous definition.
*Woman- easy right?*Christian-slightly less physically obvious, but I hope observable.*Daughter, Wife- familial in nature, one biological the other chosen (the best choice I have made for myself)
Okay, right in here is where the crux of the definition turns into how I see my personality.
*Nerd- something I have known for some time now, a vigorous curiosity about everything in the world and heavens around me, an intellectual state of mind fed by a voracious love of learning and reading.*Teacher- something I both love and in my opinion excel at, something I have had a passion for since I was 6, something I feel called to do as my explicit purpose from God.*Singer- something I dabble in, something that I do daily and immensely enjoy, something that others have complimented me on, but that I typically dismiss as a hobby not a talent.*Writer- something that you are witnessing as I type, something I do to keep my crazy in check, mostly perspective/opinion based; however, I have written a good deal of poetry, something that I do for me and rarely share in the hopes of others praise, a selfish hobby if you will.
Ok so on top of all of that, now I need to add mother. But how do I define being a mom? Do I let it replace one of the above listed. Does it completely encompass/overwhelm the others? 
I spoke with a close friend today about this very thing, and after a nap, which usually puts things in perspective for me... I have decided the following. Prepare to be enlightened beyond your wildest dreams. (perhaps that is a bit over indulgent)
I have decided to redefine mother using my definition of myself. And I encourage every mother out there to do the same. Here is my definition of mother:
mother |ˈməðər|nounA woman who through her faith, family ties, and choices will teach her child/ren the beauty of learning, singing, writing, and living life fully, creatively, and simply. A person who uses her time, energy, and arms to bring joy, instill values, and care for her offspring.
That is what I will be as a mother. I don't have to leave ANY of me behind to be one. I choose not to look with regret at the choices I have made. I will instead use them to redefine mother. To make being a mother not a change in myself, but being a mother a more intensified version of myself. To make being a mother the concentrated version of myself.
So, if I you will humor me, I will sum up myself in one word.
Jessica Cooper- mother!
The exclamation point is for added emphasis. I think it helps construe the positively life changing aspect of this sudden revelation, don't you?
Twinformation:The girls are growing. They are both around 10lbs. We are working on holding our heads up off the carpet. I have moved to almost exclusively nursing, which I enjoy because it allows time with both of the girls individually. Their personalities are so different and we get a larger window into them everyday. :) Updates will follow, should you be curious. :)
