It's a useful book, although I offer one cautionary note about this and any book on childrearing.
Young parents should not even take the baby home from the hospital until they fully understand that they are free to read or ignore all those books and articles and blogs and newsletters and church bulletins and blah, blah, blah, all floating around out there, all giving authoritative, absolute, and profoundly contradictory advice that will drive young parents crazy if they let them.
Books don't raise children: families do. The best advice I ever read about theories of child-rearing was: don't buy one book about child-rearing unless you have the means to buy them all.
Once you have the opportunity to compare and contrast, you begin to see certain themes emerge: you can distinguish sage advice from fads, fancies, and bossy instructions ("don't give in to your child or he'll become a felon when he grows up!").
That said, Dr. Turecki's approach, which was pretty novel back in the 1980s, helped a lot of parents find an escape hatch from endless conflicts between their own (and society's) expectations about the "good" parent and the "good" child, and the reality of having a child who didn't meet the textbook "norms," who didn't evolve a regular sleep schedule, who was hypersensitive, who was a picky eater, who was cranky or obstinate or whatever.
Parents who came from the rigid "clean your plate or else" school of parenting were ill-equipped to negotiate intelligently with a child who just didn't like a lot of what was on his plate. Turecki's approach gave them a way to find what the politicians call a diplomatic solution.
Parents who had been led to feel they were failures (or their children were) unless certain milestones were met on a rigid schedule, who had entered into parenting without the confidence and perspective they needed to get them through a complicated infancy and toddlerhood, got a little boost from the understanding that parenting isn't about a blueprint for "success" or "failure."
The biggest gift Dr. Turecki gave parents was the understanding that their difficult child wasn't "defective" or broken, and that they themselves weren't catastrophically bad parents if their child didn't eat or sleep or walk or talk or cooperate according to expectations.
He provided a kind of broad philosophy of accepting the reality that your baby arrives complete with an inborn personality and temperament, and that adaptation and non-confrontation gives everyone the space they needed to develop a confident, loving bond.
