Just as I was about to have my son (many many years ago) a bell went off & about 7 people I didn’t know came running in (apparently they were training), & to be honest, by that time I really didn’t care who was in the room. I think it’s great that your wife is thinking of you by having your dad there to support you.

I wouldn’t feel comfortable, but really the support team is for the husband, the mother has a whole hospital to look after her, when I had my second son, there was a couple who had her husband’s best friend there, I saw him in the hall on the phone afterwards, he was so elated and in tears it was beautiful,

If your wife is happy with her father in law present there, why not ?
The question if other mums would consider having their FIL in the labour ward is actually not interesting, this is something you and your wife have to decide yourself.

Obviously it is the expectant Mum’s idea and feels comfortable with the idea. His Dad may not wish to be in the labour room all the time but if he is in there for the baby’s Dad hopefully he can keep him calm.

my father in law would.probably k ow how to do it better than me hahah if i was close to him it would be fine. He doesn’t have to be done the business end

Personally not, but just because I haven’t enough confidence with him.
But if his presence is to help the father, I understand completely!!

I agree as long as her father in law is there for the husband and not down the delivery end, why not?

Not my cup of tea, as long as he is not down the business end, and is there for the husband – why not?
