My wife and I swore like sailors and just told the kiddo which words she shouldn't repeat because they would upset other people, and that saying them at home would make it easier to slip up outside the home. We could do it because we had more practice.
edit: I’m also one who laughs his ass off when kids swear. It’s so great
The best is when they do it in the appropriate situations too! Like an 8 year old throwing a ball and it bounces unexpectedly into a puddle and they let out a little "Well, shit." in disappointment is the best.
Me, explaining to the social special education evaluators about the words my then three year old could say and use correctly: he'll say "oh shit" in the right context
Them: both laughing We can't put that down officially, but it's impressive that he uses it correctly
Yes, most toddlers will repeat it to parrot it back and then keep doing it because any reaction from the adults is a good reaction.
My toddler absorbed "goddammit", and used it correctly! Was reaching for a toy on a high(ish) table, fell, knocked toys over, and landed in a heap. I hear, "goddammit" from behind me, and feel my wife stating daggers at me! Fun times.
