Where did my Baby go?

I had a breakdown moment today. Kassidy and I were playing on the floor. I looked up and she was walking towards me, big as ever. I scooped her up and started bawling. When did she get so big? I mean, we all knew she was walking a little, but man, I just felt (feel) sad! She took 9 steps in a row today. I can't believe almost a year has gone by already....
