Canada (at least Ontario and Quebec - can't speak for the other provinces) has taken discipline out of parents' hands. If the kids aren't happy with the discipline method - whether it's beating or grounding or whatever, they just have to call child services. The kids know that their parents have little power. The kids get their own lawyers if it comes to that. Guess whose tax dollars pay for the lawyers?
And, yeah, Babala - kids in stores. I worked as a cashier at a WalMart for a couple of years - in the States, not Canada, but I don't think there's much difference. Candy is placed at the checkouts at kid-eye level for a reason. Interesting to watch how different parents handled the situation when kids begged, asked for, or demanded a treat. My solution as a parent was to give my kids their own spending money, via an allowance some of which was earned through doing household chores. If they wanted something badly enough, they could spend their own money on it. Amazing how quickly the 'need' for something disappeared if one's own cash were needed rather than Mom's.
