I honestly don't believe that Dr. Spock would recognize today's parenting expectations as anything other than absurdity. Which it is.
No where did he say that children should not be allowed to go to a store by themselves, or that kids should be expected to have a minimum of 16 hours of college credits before they turn 18.
When he was writing, he would not have been able to imagine the way "parenting" would evolve by the end of the century.
