Mixed feelings

My baby can walk. My baby can WALK. How did this happen? She has been taking five or six steps for a few weeks now but today she has traversed twenty feet or more and boldly walks between toys and between pieces of furniture. She lists to the right quite a bit, and sometimes doesn't quite end up where I think she was aiming, but still, she is definitely walking. She has such a joie de vivre about it, too. She chuckles and giggles and grins her crooked grin and makes happy little gasping nosies as she drunkenly sways. And then I catch her in my arms and squeeze her and clap for her, but inside I am just a little bit sad. I feel like I have only gotten the slightest taste of her babyhood and it is slipping away already. I love that she can move and say things and interact with me, but I want to tell her to slow down, to let me take a deep breath and really look at her, to let me remember her and savor her before my baby is gone.
