Okay To Show Video of Delivery to Other Children
I would say this would not be a good idea. I cannot recommend you even show it to your own kids let alone someone else's. This is a great memory for you to have for yourself and your husband or SO, maybe one day for your children to see when they are adults or old enough but not something I think anyone outside of that circle would want to see. I personally would not want to see that would most definitely never want it shown to my kids.
But there are plenty of resources out there about teaching kids about how kids are born. I would look into those before even discussing the fact that a video exists.
I wished she hadn't shown me the pictures when we were done, haha!
So no, I wouldn't be showing pics or a video off to my kids. Some things are better kept private and for adult eyes.
