My niece and nephew have grown so much since I first met them three and a half years ago. They are almost different people. I've been watching my son the past few days, a little bit more from afar than usual. Partly because he can spend more time with daddy on vacation, and partly because he's busy interacting with different people.
Sometimes he seems like such a little boy. But when I get him ready for bed he's still a soft round little guy who needs lotion, wears a diaper, and wears little p.j.'s. It struck me how you don't notice day to day that your baby is going away. But one day he is. And it catches you unaware because it's not something with a deadline like a friend moving away, it's gradual.
