Why do people film births?

Ok, so I know people shoot births for themselves and their children, but why?

I can honestly say that I will die content never having to have seen a visual of my mothers private or of me coming into the world all squish and covered is nasty looking crap looking like I came out the back end. I don’t feel like I missed anything.

I am also glad I never had my either of children births filmed either. I certainly didn’t want them to have that personal of a view of my privates for years later. Hell, I was there and although it was wonderful to have created 2 beautiful human beings, I don’t need a play by play.

I know some people may get offended but my question is more for those people who say their children will want to see it some day.

Do children really like to see these things?
