That you can get sick with the contractions and throw up (so much for eating to keep up your strength) and that they have an injection to stop you being sick (finally given it after 10 hours of sickness!)
That your insides feel like they are going to fall out every time you stand up for the first few days and you want to hold onto them with both hands
That breastfeeding can be done lying down and in some cases (mine) is the only way to get them to feed, at least to start with
That breastfeeding a child with a tongue-tie can feel like having razors sucked through your nipples - get the tongue-tie snipped! It doesn't hurt the baby at all, mine didn't even whimper.
That not all MW can tell when your waters have broken, even after an internal check - I had to tell them it had happened in the loo - in fact, being naive, the waters going in the loo was such a big whoosh and such a lot of blood that I was half scared the baby was down there too!
That dilation can go from 1 - 10cm in about 2 hours, epecially when being induced
That the 2nd stage labour pains go ALL AROUND YOUR BACK AS WELL - who knew?
That standing up during labour is so not an option
That you start to wonder exactly what kind of training MW get as some of them seem to know SFA about labour - not exactly confidence-building
That getting a private room if possible is worth soooo much if you have to stay in for more than one night
