Swearing

My son will be two in October. His speech is really coming along good. However (yes my fault) he says the F word as clear as day and often. If he drops something he says oh Fu*k, if he falls over he will say it or if he can’t do something he will say “fu*k sake”.

I’ve tried ignoring it. I’ve tried correcting him and giving him different word to use instead, I’ve tried telling him no. Nothing. It’s so embarrassing. I am ver conscious now of the words that come out of my mouth but feel it’s a little too late.

Any advice? Please no shaming me
