Not gonna lie, when one of my kids was 2 she said 'fucko' and I laughed my ass off but I made sure she knew it wasn't ok to say it anymore, pretty sure she was just saying a nonsense word and had no idea what it was because I have never said that in my life. She's 5 now and I haven't heard a bad word out of her since.

Don't cuss around your kids and they won't cuss, plain and simple, don't watch Cardi B videos around you kids and they won't shake their ass, don't let your kids watch adult themed movies and they won't try to be sexy/slutty like the actresses may be in the movie. They see how adults act and they want to do that, and they don't understand that some things you shouldnt do until you're an adult, and some things adults do isn't right and you should never do.

Just my 2 cents.
