I presume mrdarcy you have not had a baby or experienced a post natal ward?
If you had you may have been exposed to unpleasant behaviour by men staying overnight. And you may be able to imagine why we do not want men to stay overnight.
But even if you can’t muster up any empathy consider this:
Just because your DH is a doctor it may not stop some bastard staring at your tits as you try to breastfeed at 3 in the morning. And no, your DH may not be allowed to shut the curtain.
Or how about some random bloke sitting right next to you, just separated by a curtain as you spread your legs to get your stitches checked or a catheter removed. And no, your DH will not be allowed to ask him to move.
Or how about your DH has nipped put for a cup of tea, you need to shuffle to the bathroom, you are dressed only in a hospital gown, you have to walk down the corridor at 2am, there are no staff, you are pretty sure you may leak some blood, you are not wearing a bra, and lo and behold, you have to stagger past some six foot bloke who you have never laid eyes on before. He could be a saint, he could be the kindest man in the world. Or he could be a bastard who is looking at you like you’re a piece of meat. The problem is you don’t know.
Can you possibly stretch your imagination to understand why the majority of people on here do not want men in wards overnight?
