The main things I wish I had been told were:
Going to the toilet after giving birth is terrifying, get some lactolose.
I was very glad someone had suggested not sitting down on the way to hospital, instead get on all 4's on back seat, lean over (while biting) the pregnancy pillow - this will help make the journey bearable.
Getting in water doesn't always help, even if you love baths - in fact it dramatically slowed down my labour and didn't help the contractions one bit.
Gas & Air, Lucozade and a frube are not a good mix....expect for curdling in your belly and being imminently sick
Take 10 times more cotton wool in your hospital bag than you expect you'll need, that meconium poo could tarmac roads. We ran out when Charlotte had managed an epic poo which actually coated her toes.
Get everyone available to help with your latch if breastfeeding. I asked on 3 separate occasions for help when midwives checked on me, I am sure that is why we are still breastfeeding today!
Good luck everyone about to embark on this incredible journey. These last couple of months have been the most amazing ever. I love being a Mummy
