First time mom here! I’ve got a pretty good idea as to what to pack for the baby’s hospital bag, I’m stuck on what I’ll need?

After giving birth how long do the drs/nurses wait to let you get cleaned up & change? Are you able to change into sweats & an oversized shirt? Or you have to stay in the hospital gowns? Do they even wash you up down there? I know I’ll be wearing nursing bra’s (if any at all) pads & granny panties but that’s about it😂

I would feel 100xs more comfy in sweats & a oversized T so I’m curious if that’s allowed??
