Hospital bag

Jenna • We had our first baby girl September 21 2015 👑 she's our world! Now we're expecting baby number 2 in Sep!!
I know it early but I'm a planner, I've been look up hospital bag list and wanted some options. 
For moms that have done this before 
After baby what to wear? 
 Long shirts/ nightgown 
Or shirts an pants? 
I feel like not having pants would be nice specially if you have a c-section watch I'm not sure what I'll have since this is my first one. But I don't sleep well in baggy thing. 
Also what are some must have for you bag this time around?
