Congratulations. Nothing you have ever done will prepare you for what follows. Protip: Babies that have issues with sleeping sometimes benefit from loud background noises being played. This due to them being used to all of the noises being produced by their mother's internal organs. You can try putting a radio off a station (for the whitenoise) and raising it to 11. Or maybe a vacuum cleaner. With my child, the radio worked like a charm.
Good luck. Being a father changes you.
