The first day after your c-section you are pretty much like a sack of potatotoes so cannot move around.
Them trying to put the robe on you and take if off everytime they need to do something is exhausting for everyone, and sore for you.
It really is better to opt to throw the robe off, just have your sheet and blanket over you, and that way everyone can take a look see and do what they need to do without it hurting you.
2nd c-section I had an allergic reaction to the morphine and developed an itch over every inch of my body that I cannot describe.
I opted for no clothes - and just the sheet over me, as my skin was on fire. They put me in a room by myself, and just put the air-conditioner on warm.
I also am a bit "listen do not look at my flabby bits" but I must confess when a baby comes out your yahoo or via the sunroof, at that point everyone at the janitor has had a look see - I really stopped caring very much who saw what and when.
I think that is what made breastfeeding when not at home also a non-issue for me.
