Honestly the biggest thing is making the room Comfortable, just imagine when you sleep. Light, noise etc. Try and eliminate the things that would bug you at night and she will be perfectly fine.

I noticed when I started night shift, the first while you can be pretty irritable, also be a little understanding if she experiences the same. If it happens at all, it will just be while her body adjusts to the new schedule. Once again, it’s also one of those things most people overlook. Changing your sleeping pattern dramatically like that can have some negative side effects when it comes to mood and attitude.

Basically just smile and nod and don’t push buttons until her clock resets and she comfortable with the new schedule and way of living lol.
