I was just thinking about this the other day, if something happened and DH couldnt be with me at the birth of our next baby, I dont know how I would do it. In saying that, when I was in labour with DS, DH was FANTASTIC!!! But I think I came to rely on him too much. When things started getting complicated, and labour was going backwards, I had to turn things around and rely entirely on myself to get things going again. My mw said afterwards that if I had continued to rely on DH to try and make me feel better I would have ended up being transferred for a c-sect. Instead I had a beautiful calm natural birth (with no drugs!!!)
But it really is something that someone has a right to tell you who should be there and who shouldnt, it is a very personal situation!!
