Delivery with husband
Recently husbands are almost always present during delivery. Men didn't have the access to the room where the woman was giving birth to the child several centuries ago. And it really had rational background. Today parents decide whether the husband will be near his wife or not.
It is good on one hand and bad on the other hand. First of all the woman needs help and support during this process, and then the husband and the future father will be very useful. But there are cases when men fainted and started to panic and of course in such case man won't be useful at all but will cause additional concern and the woman may start to worry.
But the future father is the best helper if you decided to give birth to the child together and it was not the initiative of only one of you. If the husband visited the special courses, read books and understands when and what is going to happen, he will also be able to support his wife and may be even curious about it. But at the same time the future mother must feel relaxed realizing her husband is with her. But there are women that are shy and don't want their husbands to see the process.
But be sure your husband won't help you at all not understanding how the process happens and saw it only in films. If the man is nervous and is afraid of pain and blood, he may simply faint at the moment when the child shows its head. And then doctors will have to pay attention to him and not to the child.
Remember the decision of partner's delivery must be made by both parents.
