Hubby's great-grandson pulled this stunt in my driveway about a month ago. At age 7, he should know better, but he informed us that he wanted to "beat the sh*t out of her," referring to his mother.
So I took the little gentleman aside and informed him that if he ever talked that way again about his mother, or if he ever did hit her, he not only wasn't going to get to come to my house ever again (which is a particular treat he loves), even when he was big, but I was going to have his uncle Joe blister his butt. Not much hope, though.
We shall see...
I wonder where the kids hear all of this. My almost 10 year old does know all of the cuss words, but the only time he has "used them" it's spelled out. He'll tell me that some kid said the "f-word". He'll talk about the devil being in "H-e-**".
My daughters still don't know what the "f-word" is, and they are 7.
I read that kids go through a cussing phase at 4 or 5, but my kids never have. (They did go through a potty mouth phase.)
