From practical to bigger picture.
Pack a lot of paracetamol and ibuprofen with you as many hospitals have reduced painkillers. You can cover by changeing painkiller every few hours as lomg as you don't go over daily amount for each. Keep track so you don't start feeling real pain as it is hard to keep it down.
You can buy incontinence pads as they are big and fraction of price of maternity ones. They look the same as hospital ones.
Get a nightie, if you have cathether in you cannot wear pyamas.
Drink A LOT of water, it will help you flush all drugs out and dilute your pee so when they take catheter out it will be comfortable.
Do buy stool softner. They sell prune based ones (cannot remember name!) depending on type of block you havefor operation and painkillers they give you you may have trouble going for number two. I cannot stress this enough.
Have a birth plan written as normal business document statimg your prefernece about vitamin K, skin to skin, how detailed and explicit info you want from staff (I wanted full disclosure,some people are happier for doctors to go on with their job without input, both is fine).
Have small hospital bag with your and babies essentials as you may not be able to dig through suitcase. You can keep small bag on a trolley next to your bed.
I packed premade Aptamil bottles with sterilized tits and it was saving my sanity as milk did notc) come and I had very very hungry child. Midwifes did not provide food although it was 12+h baby did not eat (in 2021st)
Bonding with baby does not depend on c section. Trauma can delay it sometimes but it can happen during vaginal too, vag birth can be brutal.
Tell your partner what help you need from him. CS is a major procedure. Make him understand that,lethim watch videos mads for medical training.
"Natural" birth is not default better. We all know women and children died before en mass.
Take deep breath and exhale slowly amd fully whenever you are in pain. Look at your baby and tell yourself you went through this to safelly bring this amazing baby here.
You are a great mum.
