It’s not overly taboo to cuss in front of kids.
There’s a difference between kids and your kids. You probably don’t want them going around saying f*ck this and f*ck that.
Infants only hear noise, but soon enough, they’ll try to mimic what you say. By fourth grade, kids will encounter every four-letter word on the bathroom stall at school.
Let me assure you that your precious 10-year-old will say every cuss word you can think of well before middle school.
Save the f-word as long as you can, and it’ll surprise you as it slips out of the mouth of babes.
