Theo Rex, at four months old, is strong and smart. He’s hungry and happy. He is a shameless flirt.

I’ve lost count of how many times I’ve been sitting in a waiting room or at the train station or anywhere, and I see a woman across the way smiling and making faces at me, wide-eyed and delighted. And I always spend a couple seconds wondering why the crazy lady has singled me out for attention before I realize – Theo is in my lap and he is sharing his irresistible grin with a stranger.

Again.
