This is very interesting and important topic. You are shared with us. The biggest effort of parents in Pakistan is to feed and educate their children well. In my opinion, feeding bad food to children is not punishment, it is spoiling their health. Yes, I can't even imagine that any parent can wish bad for their children. If a child is going in a wrong direction, then the mother explains to the kids that this thing is wrong.
parents lead by example - it doesn't mean the examples are good.
