Every time he sees Jane, Austin says "Baby Janie is so Teute!" with a huge smile on his face. He'll tell her she's SO beautiful and ask her if she's happy.
Austin loves Jane with all his heart. I'll say "I love you Austin" and he'll say "and I wuv baby Jane"
When she was brand new he'd get face to face with her and ask "do you know me, janie? Do you know me?" in a sweet, high pitched voice.
Now that they've spent considerable time together he instead says "Do you wuv me, baby Janie?"
I think she must. Who wouldn't love a brother like Austy?
