Dear OP, I've had 3 sections (one emergency and two elective). The electives were all great experiences - the operating staff are wonderful and really help to put you and your partner at ease. I remember music playing and lots of interesting conversations with the anathetists. Your baby is born after ten minutes - the next 40 minutes or so are sewing you back up but all your attention is on baby so you don't notice! Your partner and you can hold baby while in theatre. You then go into the recovery room (this is when the feeling comes back into your legs), and you can usually have a cup of tea, and have skin-to-skin and your first go at breastfeeding.
When you have the C-section you will wear a hospital gown. When you get up (usually after 24 hours) you can have a shower and change into your own nightwear. So if you're planning to breastfeed, wear a nightgown with buttons for easy access. This is better than pyjamas because there's no waistband to press on your wound, which may be sore. Slippers and dressing gown.
You still bleed after a C-section so you will need maternity pads or big sanitary pads. I'd recommend a selection of big granny pants that you can pull up over your dressing.
You will want a nursing bra for comfort and I recommend something like lasinhoh nipple cream in case you're sore while you get to grips with breastfeeding. Make sure your partner/midwives help get you comfy with pillows so you can get into a good position for feeding.
You will need shampoo, toothpaste/toothbrush etc.
You can be constipated after an operation: a snack like dried apricots is great for keeping things moving and full of iron. Lots of water or squash to sip on. Magazines/book to pass the time (newborns do sleep a lot!)
Take things easy and you will recover well. Take all the painkillers offered by the nursing staff - I was told to never let the pain build as it helps with recovery.
To travel home, wear comfy clothes. Yoga pants with wide waistband are great.
You will need stuff for baby: newborn or 0-3 month nappies, vests, sleepsuits. Mine were all born in the winter so I needed hat & outfit for them to travel home.
Congratulations on your pregnancy, OP, and very best wishes for the future. Don't pay any heed to your mother's comments. Without C-sections, both I and my children wouldn't be here. They are every bit as valid and essential as any other way of giving birth: focus on your baby and the wonderful new life you are building together
