I had an emergency c-section with my first and a repeat c-section with my second. I wanted my own Pillows. You are in the hospital longer and the pillows help so much with the incision. I used my pillows for my head and to hug on and used the hospital pillows between my knees and feet. It really made me much more comfortable.
My hospital has DVD players in the rooms, so we took a few movies, though we didn't watch many but it was nice to have, just in case.
I also took my own pajamas and outfits for during the day. Since I spent 3 nights in the hospital, I wanted to be able to be "dressed" for visitors instead of in that hospital gown all the time.
I had outfits for the baby as well, since we were there longer. I wanted them to be all cute instead of just wearing the white hospital issue shirts.
You can still have a birth plan. Make one for a vaginal delivery and one for the c-section, that way everybody knows exactly what you want. My biggest advice for a c-section if you end up with one is to get out of bed as soon as they let you and get out of it often. Walk as much as you can. Take the pain meds while you are in the hospital, I only took them at night once I went home. The walking helps the soreness so much. Take is slow and easy, but walk every chance you get. I also preferred to sit in a chair many times during the day versus just being in bed so at my meals I would always sit up in a chair to eat rather than lounging on the bed.
I also used a pillow for the car ride home, those bumps hurt!! Hugging the pillow helped.
Congratulations and good luck!
