That sounds incredibly stressful. To the point where I'm not sure if potential end results are worth it x_x
Some of them just live vicariously through the poor kids, again some time ago I also had one person telling me straight up that they were living through their kid like it was a perfectly normal and good thing (the kid had no say in what interests and activities they wanted to pursue, it was all what the parent wanted).
Isn't that why everyone has kids? To live your life again?
