AnneLovesGilbert I think they must do things differently depending on which NHS trust you come under. Not sure what booklet you're talking about but where I live you don't get anything until the booking appointment. Then the midwife gets a fresh set of maternity notes out and starts adding a few initial notes to it. She types in all your information on a computer form as she asks you questions. I think that form then gets printed out and added to your notes.
If anyone's wondering what sort of questions, it's all sorts. e.g. Have you ever had a family history of heart problems (and a whole load of other health issues), is this your first pregnancy, was was the outcome of any previous pregnancies, have you ever suffered from depression, anxiety etc, what is your home life like, are you employed, what's your job title, what's your partner's ethnic background, when was your last smear test, what medication are you on, how much alcohol do you drink, do you smoke, when did you start taking folic acid, etc etc! (Not in that order...!)
