Bex said: "I would film it I think ... not from the action end though. I'd like to know if what I remember of my children's births is accurate. And also to show the kids that I'm amazing."
But do these women ever actually watch their birthing videos? Apparently yes, and most shed a few tears when they do so.
Perhaps not a great idea to watch these while you're pregnant however, as Tyla pointed out.
"We had the camera on a tripod and it was at the end of the bed. It was awesome watching it over and seeing what I was feeling. I stupidly watched it last week ... I'm six months pregnant with number two and now I'm really scared."
Martin was given the responsibility of filming the birth of his third child as his wife really wanted to see the experience from another point of view. A responsibility which he totally stuffed up when at the crucial moment (the actual birth part) he managed to turn the camera off.
Obviously his wife forgave him for this stuff-up as this week they celebrated their 19th wedding anniversary. Martin's secret to a long, happy marriage? "It's simply finding the right person, and you know they're right if you love to be with them all the time," he says. Aww, tissues please!
