Clearly the NHS needs much better funding/organisation and ideally there would be sufficient money/space in every maternity unit for every woman to have a private room with an ensuite if she wants one or for there to be female only bays.
When I had DD (5) we had to stay in for 3 nights. DH went home when he had to leave and came back during visiting hours. This was despite DH working as a doctor on the maternity unit where I gave birth and knowing all of the staff. No one would have batted an eye at him staying past visiting hours.
However, despite quite wanting it I knew I didn't need his support and that the other women would probably be happier if he went home.
When I had DS (10) DH stayed overnight with me in a private room for the first night and then on the chair of a partially empty 4 bed bay in our local community hospital for the next two nights.
I am autistic (diagnosed when DS was two), have severe mental health issues and was supposed to be on suicide watch when DS was born.
Despite there only being 3 women on the maternity unit in the community hospital and it being properly staffed I nearly made it off the unit. I was in such a state that I was going to walk miles home in my nightie, bleeding, with no shoes or keys, at night in March. If DH hadn't been there it would have been hours before anyone noticed that I was missing.
I am not trying to prove that men should be allowed on postnatal wards or that my needs then were more important than those of the other women but I am interested in people's opinions as to what better option was. I did not want to upset any of the other women or make them feel uncomfortable at a vulnerable time for them. However the alternative is that I made it off the unit and potentially died out in the fairly rural area surrounding the hospital.
Ideally I should have been properly supervised and supported but I wasn't, despite begging for help for the entirety of my pregnancy. The necessary private care wasn't available in my area, there were no private rooms available at my hospital and so we did our best with the options available.
