Most people do but you don't have to if he's struggling to get the time off work. I didn't take dh with me. If he doesn't go though just make sure you know of any genetic conditions, etc on his side of the family.
I didn't take mine to any of them. It's a long appointment and you'll know the answers to his medical stuff anyway. Mine has difficulty getting time off anyway so I figured if he was going to be with me, I'd much rather have him at the first scan.
I'd read up on your local choices for giving birth including home birth before the appointment as she will probably ask you where you'd like to give birth.
My DH didn't. He came to the 16 week one where you hear the heartbeat for the first time and then to one towards the end of my pregnancy but only as I was having blood pressure issues and it was easier then me phoning him to come home yet again as I was being sent to the hospital for monitoring!
I didn't even think of taking my husband to the midwife appointments (or the consultant appointment, for that matter). It would have meant him having to take precious time off work just to watch me ask and answer boring questions and have my urine dipped He has just come along to the scans so far.
For what it's worth, I've never seen a man in the midwife-appointment waiting room, so it does seem to be the norm to go alone (though it would be fine for him to come along if he was free and willing!).
I don't take mine to midwife appointments, but he does come to scans. The scans are special for him too, but watching me have my blood pressure taken etc is a bit boring. Plus the midwife will run through private stuff, ask questions on how you are coping, if you are feeling down, if you have relationship problems you might need help with. Some women are grateful to have the chance to discuss this away from their partner.
DH came to some of the scans with my pregnancies. I wouldn't really expect him to take time off work for appointments, unless it was a follow up for something worrying. Tbh when things get stressful I prefer him not to be there.
My DH came to pretty much all my appointments for DS1 - mainly as his work was directly across the road from where the community midwives were based. I think at the first appointment they asked him about family history and about his alcohol consumption and smoking etc. Rest of appointments it was more so he could hear the heartbeat as well.
This time, he's only been to a couple of my appointments as midwife is based in different area of town and his work is less sympathetic to pregnancy appointments.
First time through I dragged brought DH along. This time, even though it's a pg identified at-risk, I've left him behind. There are always long waits so I prefer only to incovenience me rather than us both. Some of the novelty has worn off too, plus, of course, if DH is at home he can look after DS. A little break for me .
