1 That often, epidurals only work DOWN ONE SIDE. This means that you are incapacitated, lying on a bed, but still in f*ing agony. (Though at least I couldn't feel the crowning part.)
2 That most of the hospital midwives may be young enough to have not had children yet, and therefore will be utter shite at gettting your baby to latch on with you.
3 That the last thing you may want is your mother, sister and brother crowding around you in the hopsital for the following two days, while the hospital neglect to tell you that you are so anaemic it's just ridiculous, and will only give you iron tablets on the third day when they send you home after days of agonised staggering to the bathroom in a pathetic attempt to wipe yourself with a flannel as a shower is too much.
(and 4: Hospital food is the shits, and there isn't even very much of it. You will need outside supplied. Also, the 'creamed potato' as recommended by Lloyd Grossman is the worst thing on the menu. The cleaning staff are often more friendly than some of the midwives, too.)
Oh, and that if you shave your undercarriage, there is less chance of the stitches snagging on the hair down there. I'm going in prepared this time.
