I am always introducing both of my kids to metal. I am not doing it on purpose. Just so happens they are around it, riding with me in my car, going down to the basement where my music setup is, etc. So, they have heard what different metal sounds like, from classic to death to black. My little guy is more of a "headbanger" than my older daughter is. When she was little she was into lots of heavy and crazy stuff, but the teenager phase and what the girls are listening to at school, on her swim team, etc. has an "unfortunate" effect for her to drift out of the quality metal realm.
