If I had to be saddled with a kid....
-No smartphone.
-Any internet usage is on a common computer and monitored like a hawk.
-No Tik Tok or any other retarded social network shit. Make them get to know people personally.
-Video games are fine in small doses and if quality control is enforced.
-Encourage playing outside and some tabletop gaming.
-Read to them as soon as possible. Encourage reading, fertilize it once they find a genre they dig.
-Get them into something physical. Sports is fine in this regard as long as they keep it in perspective. Even if they suck at it, still encourage it for the other benefits.
-Teach them basic bitch life skills like cooking, laundry, sewing, some gardening, how to buy a car. School sure as shit ain't gonna.
-Teach child common sense about sex and relationships. Masturbation is fine if kept private. Sex, while not evil, is far too much of a risk until they are stable in life and preferably married.
-If my daughter comes home with another girl as a date, I'll take the other girl hunting with me. If she's good with that, she's good enough for my daughter to date.
-If my son brings home another boy, he's going shopping with my wife. If he makes a good impression on her while doing that, he's good enough for my son to date.
-Troonery will result in therapy.
-Pedophilia will result in therapy or enrollment in a monastery away from children.
-If child is kinked, teach them about privacy and consent and not to foist it on others.
-Let them choose religion on their own, support it as much as I can muster, but emphasize to not be a douchebag about it.
-Let them always know that I and their mother love them always (even if, at times, we don't LIKE them), and will do our best to protect them if they are victimized by something or someone.
-Above all, teach them to own their shit and that actions have consequences, and you do not blame others for your fuck ups.
