There are trends in parenting. At one point, it was a common belief that children should be treated in a manner somewhere between training a military recruit, and breaking a horse. Then, the pendulum swung to the far opposite. I recall in the 1990s a prominent commentator in the national newspaper writing an indignant article because his daughter's dentist had told him to "make" his daughter brush more frequently. How horrible, he proclaimed, to think that a parent had the right to make a 10 year old do anything, even at the expense of serious dental problems down the road.
I hope that, for the time being, we have reached the Golden Mean, where discipline and kindness can both be used, as best fits the situation.
