I agree with much of what you have to say. And don't get me wrong I see bad parenting all the time (yes I am judging) but nobody knows the circumstances of each child. We often fall into the trap and bemoan the loss of the old ways but the bygone era is far from always correct. Advances in the sciences of brain development and nurturing isn't some giant liberal agenda to create a snowflake society. Technology has changed what society we live in today. We don't need the same skills to live and thrive as 500-200 even 50 years ago.
I was the kid that got up in the summer at 7 AM grabbed my bike and was maybe seen again at lunch or dinner. If I got thirsty I ran to a neighbors back yard and grabbed a hose. Give me a bike and a stick and I could make a day of it. Depending how you look at it, unfortunately that is not the world we live in today. Is it creating a lesser society of peoples, eh,...different but no necessarily bad.
I am a parent of 5. So even 4 hands are not enough. On top of that, 2 of my kids have ADHD. For many (like my previous self), I thought that was some made up diagnosis that just meant it was a kid being a kid(maybe a little hyper). It absolutely is not. My kids look exactly like any other healthy 6 year olds but they do not have the ability to sit still, listen to a simple instruction and do not understand how to moderate their emotions. Fear, time-outs, calm talking, misdirection, hitting, none of those tactics work. Going to the supermarket takes the patience of a saint. And I'm sure I may look like I am a bad parent when there is a almost 7 year old crying on the floor and the other one is screaming and running down the aisles(there are good and bad days). BTW, tried tethers and they didn't work for our kids except to closeline unsuspecting children.
