I was able to use a surprising amount of the stuff I got while I was expecting a vaginal birth. I didn’t need too much stuff.
C-section ice packs. They really helped my incision pain.
I used these, frankly, diapers because they reduced how often I needed to bend down. She’s going to going to be bleeding like she’s on her period for weeks and you can take these off by tearing the sides. It was easier than the mesh disposable underwear I got from the hospital. (TMI, but I didn’t know you still bled vaginally after a C-section.)

Maybe some cute compression socks. I had crazy swelling in my feet and legs for two weeks after my C-section.
