Congrats sir!

Switch to eating fruit (and other raw foods) at least 70% of your total intake.

Your energy levels will go up and your sleep needs will go down.

You'll need that in the beginning to be a solid support for your partner and the baby.

This will allow you to be extra patient and empathetic with everyone, which is what you'll need.

You'll also enjoy this process (if it's even possible) at least 50% more than on crappy energy levels.
