Baby clothes for hospital?

What all do I need to pack for her for the hospital? I know her coming home outfit, which I am planning on something comfy but girly cute. But should I pack a fancy dress for pictures in the hospital or would just a cute onsie outfit be okay for pictures? What has everyone else done or plan on doing? And how many outfits should I pack? FTM due at the end of April and pretty clueless how everything works. 🙈
