No author and reader will ever totally agree on parenting philosophy, and as a non-Christian he obviously misses the whole issue of sin and grace in parenting, but a lot of the book is just pure gold.
Here's my favourite bit so far, which describes his psychology session with an 8 year old who won't sleep in his own bed, and his parents: (transcribed without permission from pages 98-99)
'What do you enjoy most in the whole world, Jordan?' I asked.
Because he had no idea that he was setting himself up, he simply told me. 'Soccer.'
'You like that the most?'
He nodded. 'Soccer is really cool.'
I could see it in his eyes - this boy was mad passionate about the game.
'OK,' I said, turning to his parents. 'When would you like him sleeping in his own bed?' I asked it using a tone which said that this would be no problem at all - they just had to choose the night. I used this tone for two reasons: first, to instil some confidence in both them and their son, and, second, because it was true.
They looked at each other, before Petra said, somewhat hesitantly: 'As soon as possible.'
She smiled as if she wasn't sure I was serious. 'If that's possible.'
I turned back to Jordan. 'How much do you like soccer again?'
This time he answered a little less certainly, because, being a very bright young man, Jordan had tumbled my game before his parents had. 'Umm... quite a bit.'
I laughed. 'You're a smart kid, Jordan. What do you think I'm going to tell your mum and dad to do?'
He gave me a conflicted frown, because he was pleased with himself for figuring it out, but in the same breath absolutely opposed to the idea. 'That I can't go to soccer unless I stay in bed?'
I smiled broadly. I liked this boy a lot. 'Bingo.'
