I understand the logic behind it but no dad should be deprived of the right to see their child born.
And here is the problem in a nutshell.
Firstly: Whatever about the mother, the father does not have a right to see his child born. If there is emergency medical intervention, he has no right. If the mother doesn't want him there, he has no right. If he is potentially carrying a deadly disease, he has no right.
Secondly, birth is a process which involves getting the baby out of the human body. It is not a religious experience, it is not the most important part of parenthood and it is not something where the joy of the experience should outweigh medical priorities. The aim is to get the baby out safely. When I had my EMCS, they didn't wait for DH to get there because it was medically unsafe to wait so I had the baby on my own.
People have to stop prioritising their personal wants over the needs of others.
Otherwise this virus is never going to get under control.
