I guess parenting is a touchy subject, but I have many friends who now regret that attitude now that their kids are teenagers. I'm not saying you jam broccoli down D4s throat, but if it's your time, and you don't want OM around, you stick D4s butt in the car.
Kids crave appropriate discipline and boundaries. I went back and read and your permissiveness with the kids seem to translate to W as weak willed over all.
