I wish someone would have told me the following (maybe they did and I just didn't listen!!):-
The blood after the birth would resemble a horror movie. I nearly passed out from the sight of the blood when I stood up for the first time. I am not even a little bit squeamish normally but I could not believe the amount of blood that came gushing out.
You can't eat soup with 1 hand.
You will only have one hand to eat with or do anything else. If you a right handed, your free hand will be the left one!!
Buy plenty of little snacks that you can just pick up and eat.
Breastfeeding makes you hungrier than you have ever been in your life.
Get a subscription to Lovefilm or Netflix.
You will be more tired than you have ever been in your life (I know everyone tells you this but I don't think you realise how little sleep you will actually get).
Coffee & sugar are your best friend in the first few weeks. You can worry about your waistline at a later date.
People will arrive at your house whenever they feel like it.
Don't bother with newborn clothes other than sleepsuits. They won't wear them.
Muslin cloths are amazing. Make sure you have plenty.
Buy some bottles and formula, just in case. After 3 weeks of breastfeeding, I sent DH out at 2 in the morning to fetch bottles, formula and a steriliser because I couldn't take the pain anymore.
Speaking of pain, stitches in your hoohaa REALLY HURT!! I found the pain from that worse than labour and birth.
Good luck!!
