A "My Baby Is Growing Up" Moment

Earlier today, I asked Little Girl to turn a light off, and for the first time ever, she was able to reach the light switch on her own without getting a step-stool. She was on her tippy-toes, reaching it with the tips of her fingers, but she still did it. I wasn't ready for the sadness that came with that little event. She's growing up more and more all the time.
