I did the same with my boys -- now both software engineers (duh). When raising children, are you going to omit how Physics affects your life? No, you'll tell about hot stoves and heavy objects on the other side of levers. You tell them about chemistry and biology: frying pan fires, food going bad, drink fluids when you're sick. We tell them about history and sociology: this group of people came to this country when they were being murdered in their own country; that group came because they were granted land by a government. We omit money and how it works. Many also omit romantic sex, even if their kids take sex ed. And, of course, we omit anything that we don't want to face ourselves, but that's probably another topic.
