Those delicate parenting moments

So recently my sons new thing is putting his hand in his underwear every time he farts....

Mfw i realized he was doing this:

I muster up the courage to ask a 4 year old *calmly* why on earth would he do that?

"Because it's amazing"

I obviously explained to him that it is absolutely gross to do that, and to stop. Where do kids learn this shit 🙃
