My hospital gave me big net knicks to wear and I asked for a couple more which I just handwashed. Ask your midwife if they have any.
Take some music to listen to.
During the spinal dont be alarmed if your legs get shaky and you start shivering, its just the anaesthetic working.
You will feel rummaging but no pain.
You will be surprised when they show you the baby so quickly. Mine was born within what felt like 10 minutes after the op started.
In recovery you will be drugged up to the eyeballs so best not to phone people if you dont want to be reminded forever after of the crazy nonsense you were spouting.
Ask for a bedbath the day after.
If you have any weeping from the scar tell them. If it continues after a few days ask for antibiotics.
Drink lots of water, take a fan and wipes. Snacks, nappies etc within easy reach.
Ask them to swaddle the baby and keep beside you, saves you lifting in and out of the cot.
Once the catheter is out do some shuffling walking around.
Good luck. My ELCS was the best calmest loveliest birth and recovery far easier than my previous EMCS.
