My c/s was an emergency so I learnt alot the hard way since I had no opportunity to prepare
I would second all the advice here particularly about the big undies! When you buy them put back the pairs you are going to buy....and go ANOTHER size up. They can't be too big!

And definitely go the pain killers. But be careful. My OB warned me that I would probably feel pretty good the day after the c/s because of pain medication still in my system and it would be day 3 that would be the shocker. He was soooo right. I overdid it a bit on day 2 thinking I was fine and on day three I totally hit the wall as well the 3 day blues setting in so beware of that.

The other thing I would add is most hospitals have a physio come to see you after your c/s to show you how to get in and out of bed and lift baby etc without hurting yourself. Listen to every thing they say and do it and you will be a whole lot better off. Their advice made a world of difference to me, before I saw them I was really struggling with getting up and then they showed me how and I had no more problems.

I think the main reason to have your dH there in the first couple of nights is because it takes a loong time to get yourself out of bed to pick up the baby and feed and if he's there he can help you. You will be moving like an old woman at first. Otherwise for the first night at least you will need to call a middie which is a bit of a pain when bub is yelling.

Oh yeah definitely get up and move around asap. I had my c/s at 3pm and at 6am the next morning as soon as I woke up I buzzed the middies and demanded they take out my catheter and drip because I was having a shower LOL. Best thing to do.

Good luck for your birth
