22 month old baby saying 'bad' words

I am a single parent. My son is 22 months and has picked up a few 'bad' words. How do I get him to stop?? I've been trying for a few weeks now and nothing seems to be working

Elise came out with a few bad words, but i told her that only mummys were alowed to say bad words and it worked!! but i aslo shouted at her for saying them to,

hope you stop him from saying them! its well embarasing when elise does it in a shop! i want to crawl up my own bum LMAO!

I would ignore him and not engage in conversation about it, if he sees he is not getting a reaction he might stop it.

I get upset at my son for saying them... he also hits when he swears. It is really embarassing especially when he says them at daycare the workers aren't too impressed with that.

my girls have picked up a few sweary words recently and i tried ignoring it when that didnt work i simply took them through the bathroom picked up the soap and threatened to wash there mouths out with it (they know i always carry out my punishment threats although id NEVER really do that).bad words have never been heared again

My DD started sating ba words - we just ignored her and they stopped but if that didnt work i just got ehr to say something else - like when she got frustrated once and said "for f*** sake" i just said "oh dear" and she repeated what i said and i just did this each time til she forgot what she was saying!
