Hello. Please don't worry, it is remarkably calm. My DD was emergency c-section, which is not pleasant, but DS was elective and the whole thing was very civilised.
It is a bit surreal arriving for an appointment to have your baby. I was nervous - a bit like on the morning of my wedding .
Get very high pants a size or two bigger than you think. Have generous jogging bottoms that do up round you WAIST (ha ha, remember that?) not you HIPS. You won't want anything touching the general vicinity of your scar for a while.
I had about 3 packs of extra large paper pants. These were great - you can ahem, freshen up more often. Even though you aren't having your baby vaginally, you will still bleed in the same way. I think those maternity pads are a load of old crap. Buy yourself Always night times, they have a sticky strip to keep them in place - the maternity ones don't.
This is possibly TMI, but have some moist toilet tissue or a big packet of baby wipes. You can't get out of bed for a while and it's not nice simply having your pad changed by the midwives - having these means you can again, ahem, freshen up with some independence. I took nappy sacks to put all the stuff in and DH would chuck them in the hospital bin for me.
Take your own pillow, with your softest most homely case on it.
Take a feeding pillow of some kind if you are intending to breastfeed.
If you are intending to BF, tell your midwife that you want your baby on your breast within half and hour of birth. To try not to let it go beyond the "golden hour". Keep putting your baby to your breast whenever you can. It can be hard, as my first BF with DS was whilst I had a BP cuff inflating and deflating every five seconds and DH kept having to take the weight of DS, but I was determined. I learned a lot from the disaster of DD's birth (I did not manage to BF her).
If you are in NHS hospital, get DH to bring in flask of nice pea and ham soup or something. You NEED fibre and roughage. They don't tend to want you to go home before you've done a number two. Very hard on a diet of rice, pasta and chips with some naan bread .
Have some nice spritz or something for your face, and some nice moisturizer. If you normally wear make-up, pack some. You'll feel better and more human leaving the hospital.
If your feet have swollen, don't assume they go down immediately after the birth. Pack shoes you are wearing at the moment.
Take a CD and pick a song to have your DC to. They are generally very accommodating.
I assume you know you will be having a catheter - don't worry, it doesn't hurt, it's just slightly odd sensation going in.
When they take it out, you will do a wee in an odd shaped bottle. The volume of this wee will fill you with shock and awe.
Be sure to have them position your baby in the cot very close to the top of your bed. Make them check that you can reach your baby before they go away. You have very little movement to start with - the last thing you need is so be in pain, reaching for your little one when they first cry out for a feed.
Make sure the cord for calling the midwife/button is in a place you can reach it. I kept knocking mine to the floor...
You can't eat for a while before hand, or after, so make sure you have something you will really and enjoy and deserve, on hand for when that moment arrives!
Good luck - it is an amazing experience. I'll give you DH a medal if he manages to watch your DC "come out". My DH was asked to stand up to see DD and tell me the sex...his legs gave way, he threw a complete whitey and burst into tears sobbing "it uh, uh, gggggirlllll".
Have I written enough now? I could write me a book.....
