I gave birth 11 weeks ago and I could still describe it graphically if you like? Haha
At my baby shower I was given a jokey "labour survival kit" ... inside were granny style 18-20 knickers. I'm a size 10 and returned to a size 10 quickly afterwards- I wore those knickers just after the birth and for several weeks afterwards. I think you just need comforting pants :-D
I had to stay in hospital so im not sure- I'd maybe take 7 pairs? Your other half can always return home for more if you need to stay in.
Dry shampoo- because I stayed in- i didn't want to wash my hair but i didn't want to look like a greaseball either. Ps- since giving birth I've had relatively greasy hair- never suffered with this. Also, i think when people tell you that you will "lose lots after hair"-It's a myth. Reality is you'll just not have time to brush it so when you finally do there's a lot of hair that's there.
I thought I would have unicorns skipping around the room underneath rainbows whilst I meditated through labour. This did NOT happen. I was determined not to have an epidural - and I didn't- but if I were to be induced again I would seriously consider this. So stay open minded 're pain relief.
Use gas and air as soon as you need to. I stupidly thought if I used it too soon i wouldn't "feel like benefit" later on. Not true. I did have to concentrate when I was using it right at the end because if you don't breathe it in as you're supposed to you can't keep on top of the contractions (I lost my mind on several occasions).
I was induced which I can only describe as agonising (others may have a different experience). However, I don't know why it's not used as a torture method. Early on in the induction i spent a lot of time googling induction (stupidly) I wish id had a magazine/netflix/kindle.
No one ever told me that you can get contraction in your legs-this really took me by surprise (thats a mild description of my reaction) so I just wanted to warn you.
Take an extra nightie/pjs and extra slippers. Mine were destroyed in the massacre that i appeared to be the centre of.
I write this tongue in cheek/aiming to be light hearted/jokey about birth. You will never experience anything as incredible in your life. You will be blown away by your body's ability to deliver another life and by your own strength. No matter what you go through (easy/difficult labour) you would do it ten times over to meet you baby.
