How to take care of belly button piercing?

Fa

Hey loves! I’m gonna be getting a belly button piercing soon and I was wondering if anyone has any tips or tricks on how to take care of them .the biggest thing I’m scared about is I’m a stomach sleeper and I lay on my stomach a lot so any tips on how to not get it caught on anything or how to keep it clean constantly I would appreciate! also when can I change the jewelry out ?
