I dropped my three kids off at school last week and sat in the car for a minute longer than I needed to. I do not know if it was the new backpacks, or the way my youngest walked through those doors without looking back, or just the particular quality of that morning light, but something about it hit me differently this year. I kept thinking about how fast it is all moving. How the babies I brought home from the hospital are now packing their own lunches and losing their teeth and having opinions about their outfits.
