I discussed this because "Price of Privilege" was brought up in the topic.
And it happens to be front and center of something I am doing. Her point is about doing for your child instead of them doing for themselves. So you arrange playdate with KidA, drop them off at 3:30 and pick up at 5. Instead of DD going out the door, finding KidA and KidB, maybe C. Then they brainstorm what to do, do their playing and DD knows she has to be home by 5:30 and has the responsibility of coming home instead of me looking for her. Not that they don't do a little brainstorming about play but the huge amount of toys in the house helps. Instead of meeting up emptying handed and figuring out next steps. Levine thinks that these simple steps help build the skills necessary to survive. And the parental arms race and blueprinting each year through to college creates a problem in college and beyond.
Since reading the book, I have taken a conscious step back and said, "figure it out," I can't always fix it, when I can.
