Tips to calm baby?

Celeste • Pregnant with baby #1 EDD April 3rd, 2016!
Our one week old boy is starting to become fussy a lot and is inconsolable at times. As a FTM we have gotten a lot of advice I would never think of (ex: rub their tummy, play white noise, etc). Any tips you can give a FTM for when my little man is crying? (Knowing their needs is first obviously...I'm talk about when it's not hunger, a dirty nappy, etc)
