I am married. Would it be insane if I just became a father for the first time a few weeks ago?! I wouldn't be looking to formally start something until early next year though.
EDIT: Forgot to mention that my spouse would have a big say in this too.

Just make sure spouse is truly on board. Your stress is their stress and vice versa. I might add that my wife ended up getting a graduate degree and a new career, and the experience brought the whole family (3 kids) closer.
