Yes! My toddler already knows what is good or bad, and I just find it funny sometimes when I unintenionally curse beside him. He would always tell me, "Mama, don't say that. That's bad." Good thing, he doesn't imitate what I say. haha I have this little MTRCB at home LOL
I would also say sorry afterwards. At least he knows that I really said something not good and he won't say it as well.
