And then one day you look up and he’s 5. Diapers have become super-hero undies. Babbles have become conversations about robots. Waddling has become soccer practice. You’re exhausted most of your waking hours, but you don’t take your eye off anything, for fear you’ll miss it. And then a hectic day becomes a peaceful night, and you’re struck by the miracle of it all, the profound love and happiness. He looks at his new toys and says, “Good night, Batman. Good night, Robin. Good night, Captain America.” He tucks away his cape, kisses you and says he loves you. And tomorrow, you can’t wait to do it all over again. Happy birthday, Luke.
