When our first child was stillborn we were put in a private delivery room, which also had a bathroom, small kitchen area, and a sofa bed.
We could have stayed in that room together overnight, but I was physically well enough to leave and we just wanted to go home.
When our second child was born prematurely we were put in that same private delivery room again, because they knew that she would die either during or shortly after labour, and this time we did stay overnight because I was also very ill. She died two hours after her birth while we held her.
However for the four nights previous to her birth, I was in a private room on a normal ward and DH did not and could not stay.
Even on the night they told him I was so ill from the infection to my placenta that they needed to deliver the baby the next morning or I would die along with her, he didn't get to stay. Not until we were moved to the private room especially designed for partners or supportive family members to stay alongside the patient. They let him stay longer than the normal visiting hours, but he went home or to my parents house nearby rather than stay overnight.
We stayed in that room for two nights, and then it was either back to the private room on the ward or home. I chose to go home against their advice because I just wanted to be home, not because DH could or could not stay.
So they can and do make exceptions when circumstances are so extreme as to need them, but only when they can really accommodate partners without causing problems for the other patients in the hospital.
And even considering everything we've been through, even on the night they told DH he had to prepare himself for losing me as well as our daughter, they had to consider those other patients needs as much as they had to consider ours, and I still think that's the right thing for them to do. The times DH was allowed to stay only worked (for everybody, not just us) because we were isolated in a special room reserved for the most tragic circumstances, well away from the main wards.
They can't provide rooms like that for every patient. There just aren't the funds or the space or the resources or the staff. Our hospital has just the one room like that in the women's hospital, and if another family experiencing a similar loss had needed it after our daughter was born I would have been moved and DH sent home. As is only right.
I've already shared my story of how awful one man was on the four bed ward when we went on to have DS, and how I couldn't walk and felt trapped and frightened.
Everything was a struggle and help from DH would have been nice, but I still think properly staffed wards would be better than wards filled with non-patients 'helping' to various degrees. They can and do make exceptions when circumstances really demand it, but also they need the right facilities to make those exceptions, and a single room at the end of a corridor or a curtain around a bed just aren't enough sometimes to allow them to do so.
To me, the safety of all patients has to come first. They really can't guarantee that with non-patients spending the night. There've been so many examples on here of women in labour or with newborns being intimidated and frightened by partners of other women to make this a justifiable risk in my eyes.
