He is growing up!
It hits me in sudden waves of realization. He is such a little person! He acts so grown-up. Good manners. Polite. Helpful. Considerate. Thoughtful. Caring. It's amazing… He is definitely not my baby boy anymore… the toddler stage is long past… he is 100% little boy! And sometimes "little" doesn't seem the appropriate description. He makes us laugh with his proclamation of being "a grown-up" and what "grown-ups" do/like and don't do/like… he's not grown-up yet, but he is on his way, and will most likely get there before I am fully ready for it…
