Wife and I have had a few discussions about this. Ours is 6 months old so we’re sure some things will be coming back to haunt us in the near future. We’re ok with it. As it comes up, he’ll be taught what adult words are and not to say them. Inevitably he will surely say something at daycare or school and we’ll have to deal with it but oh well. It’s words. Don’t really care that much. And honestly, I foresee myself getting in trouble for laughing at shit he says in the future.
