There is a video doing the rounds that will make some laugh harder than others.
As parents, we laughed so hard we couldn't speak and our faces hurt. Those who don't have kids might have a chuckle, but really, you just don't quite get it.
Michael McIntyre is a British stand up comedian and TV host who demonstrates the difference between life with kids, and life without, in this clip called "People with no kids don't know".
Enjoy.
