We live in a society which at once affirms both the supremacy of nature and nurture with regard to raising children.
Children are apparently born the way they are and its wrong to change them; but parents are to devote all their time and resources providing opportunity and experiences which will enable them to grow into the adults their children will want to be.
When I was a kid everyone thought we’d have all this extra leisure time in the future because of technological advances.
No one seemed to think that parents would need all that time and more simply to manage their children’s life development.
This is from Kevin DeYoung’s Crazy Busy.
Parenting has become more complicated than it needs to be. It used to be, as far as I can tell, that Christian parents basically tried to feed their kids, clothe them, teach them about Jesus, and keep them away from explosives. Now our kids have to sleep on their backs (no, wait, their tummies; no, never mind, their backs), while listening to Baby Mozart and surrounded by scenes of Starry, Starry Night. They have to be in piano lessons before they are five and can’t leave the car seat until they’re about five foot six. It’s all so involved. There are so many rules and expectations. Parenting may be the last bastion of legalism. Not just in the church, but in our culture. (p. 67)

The ‘rules’ leave little room for parental guidance and correction, they tend to encourage ‘self expression’ by the children, who at their age have little concept of possible consequences of behaviour.
