But big sis is such a comfy pillow

I'm afraid you need to go to the site to view the video properly.. it seems truncated here.

Not funny at all!
I cannot exclude the operator of the camera (parent, babysitter... whoever) is in legal trouble - making movie instead of putting the baby in a comfortable bed. And changing his pampers - it's definitely full.

You may be right, but I think that's an over-reaction. If babies are uncomfortable or distressed they tend to cry.

Is it mandatory?

There are some things and situations we cannot make fun of. It is an essence of humor and taste. And the culture of mutual anxiety and compassion.

well I think its cute!

Yes. Very cute.
