Why can’t parents just put their hands on their baby’s mouth to stop them from making loud noises when crying in movie theatres and airplanes?

Question

I have always wondered this but never wanted to directly ask a parent as it could come off rude.

It makes sense to me though, like when people cover each other’s mouth’s in movies to muffle whatever sound they’re making.

Edit: I would just like to say that I would never try this, I was just curious!

It simply doesn’t work.

When I was a *very* new father my baby suddenly started crying loudly in the middle of a wedding I was attending (my wife was a bridesmaid). I tried putting my hand over his mouth and it made absolutely no difference at all. Then a totally unknown woman sitting next to me just picked him up and held him. He stopped immediately.
