It's quite clear, from the amount of professionals who have answered your questions and tried to reassure you that you're not going to understand the relevance of the questions, and maybe just have an issue with the Midwife/the system in general? Or, due to your lack of comprehension, are exactly the person that the Midwife is trying to assist by asking these questions?
I've had to be the one asking those questions before. Believe me, we don't enjoy asking them, and ideally they should explain what the questions are for.
Maybe be grateful that you can answer those questions and the answers are pretty run of the mill? Because by asking those questions I have identified:
A mother in a new relationship, whose partner had been in prison for shaking his ex's child. She didn't know.
A couple who were first cousins, who wanted to have extra screening (didn't realise they could) and whose baby was identified as incompatible with life and they were then given choices and options they may not have been aware of.
A military spouse who was literally about to move to Germany. Because we knew this information we gave her all her information, photocopied and signposted her to what she would need to do maternity care wise when she moved.
Oh, and also, God forbid anything happened to her at an appointment when he was deployed, we had his regiment and battery details so we could make contact with him. Hope you don't think that's too invasive either?
We've identified a 23 year old mum whose partner was 60. Turns out he wasn't her partner at all but her sex trafficker.
Conversations around housing have led my colleagues to be able to provide letters of confirmation of pregnancy to help women get better accommodation.
Conversations around financial concerns help us signpost to benefits.
Do you feel safe at home/how is your relationship? We should be asking this at every appointment because we know statistically that women don't access help the first time they're asked,and we have helped women in violent circumstances.
The fact that YOU don't see the relevance of the questions probably means you're in a bit of a privileged position, but we have to ask them to help people who aren't in such rosy circumstances.
If you have an issue how about you raise it properly through the Midwife or through PALS?
