To beating wing

I climbed out of the eternal

And into the shape of me 

Some words I wrote years ago when I was thinking about my own mother. And the woman she was when she had me. And the woman I was reaching to become. The shape your desires make out of you. The body you become to hold your dreams. It's with two feet firmly on the ground and a heart swelling in an ocean of love that I'd like to share the new shape I am becoming to hold the greatest dream of them all. #babybump#newparents"
