Here's what we know about Carrie Underwood's son Isaiah as he gets close to his seven-month mark:

1. He is already sitting up, and rocking a little blazer (as evidenced by this Instagram picture Underwood posted a week ago).

2. He is kind of a morning person. "My son — he's the happiest little thing in the morning. He wakes up ready to go and smiling and laughing. It makes mornings a little sweeter," Underwood said during an interview with NBC's Today.

3. He is likely going to be the topic of at least one song on her upcoming album Storyteller, due out Oct. 23. "It would be impossible to not let your life kind of work its way into your music," she told Today.
