How to teach girlfriend to use controller?

Genuinely need help.

Finally convinced her to play a game with me, It takes Two, but it’s driving me up a wall trying to figure out how to explain to her to use the controller properly.

She doesn’t understand yet how to use all the buttons and joysticks fluidly. It’s one movement after the next. She moves feet, then moves camera, and she’s dying a lot because she doesn’t look at her environment before going somewhere.

She also struggles to remember where buttons are and misinputs a lot.

Does anyone have any suggestions on things she can do to get the hang of it better? I assume it will come in time, but I’m wondering if anyone has experience on how to explain how to use the controller better so it will “click” for her. For me it’s like trying to explain how to breathe, it’s just second nature.
