Interesting squiz - I wonder if the OP has some similar circumstances?
OP - At the risk of appearing rude, is English your first language? I ask because some of the phrasing you've used sounds as though it is a case of saying one thing, but possibly meaning another, and that's getting a little "lost in translation".
I also think that you're getting some of the different themes on the thread muddled. You now realise that the actual birth bit is not going to be a five-minute puff/pant/pop situation, and that your wife may feel shocked/elated/traumatised/physically damaged/unchanged by the actual birth experience. The point is - the whole situation is unpredictable.
It is not a case of 20 minutes from waters breaking to onset of labour, labour lasting 3 hours, birth taking 40 minutes....
Also, once the physical birth experience has taken place there is a whole raft of hormones hitting your wife's already exhausted system.
The hospital may not have a visiting room. The one I delivered my DD in didn't. Visitors were permitted between set hours. They stood/sat beside the bed and you could pull a curtain around for "privacy". On a ward with 30 other new mothers/mothers to be. Where relationships are strained, this is NOT a helpful scenario.
It may be that you're using a hospital where you wife has a private room in which case, that may alleviate some of the pressure.
BUT - and this is the key thing. YOU are no longer the centre of your wife's world. Your newborn child is. Your wife has grown this infant inside her body for 9 months. She has probably felt tired, stressed, sore,nauseous, unattractive, incapable of things as the pregnancy has progressed.
Suddenly, the child is outside her body. Whichever way it is delivered, she is bound to feel that she had little control over the experience, and overwhelmed.
On the ward in the hospital there will be little opportunity to rest. The midwives/staff will be encouraging her to 'bond' with this newborn infant. It is likely to be red, angry-looking, and cry a lot. A lot. And then it will probably cry some more. As will all the other babies on the ward.
The ward will be hot.
Your wife will be sore.
Your wife is not likely to get any sleep.
If your wife ends up staying overnight or longer, she may not get much to eat/eat at the times she wants.
Depending on the delivery, she may be checked by medical staff regularly. I don't mean they will get a stethoscope out and listen to her chest, I mean they'll be looking at her most intimate areas to assess healing, etc. Her toilet visits may be monitored/scrutinised to ensure they are 'normal'. This can be embarrassing.
She may be encouraged to breastfeed. This will take time to get used to. It is upsetting, frustrating, and exhausting.
The baby will need changing. The nappy will be scary. The wound on the baby from the cutting of the umbilical cord may look scary or sore.
She may feel that the medical staff expect her to know everything from the start, and she may feel out of her depth.
In fact, every single thing in those first few days is an absolutely monumental learning curve and a sense of overwhelming responsibility.
If your wife is hoping to continue breastfeed your child then she may need time to acclimatise to doing this. She may want privacy. She may need support. Or, she may decide it will be easier to bottle feed. Or go with a combination. The hospital may make her feel that any one of these decisions is better than another. And the baby has to learn to feed.
What I am saying is that nothing is going to be simple, and much will be out of your (and your wife's) control.
So... the best thing for you to do is to ensure that anyone coming to visit is on her terms.
Having visited family members with newborn children, it really is not that exciting. It's always been much better a few weeks on when they're settled in their own home, and have had some sleep.
