This was the right book to read after finishing his biography. The Author of his bio. used many quotes from this book. I don't find Winnicott to be a difficult writer, in fact I like his style very much. I think he has a wonderful mind and I can see why so many people from different fields of thought have gravitated toward him. He puts things in a kind of, well I hate to use the word Post- Modern, but at least a perspective that appeals to a generalist; someone with a very basic layman's understanding of Quantum Theory, [ie. on the level of having read The Tao of Physics] for instance.
I loved the way, at the end of the book, he both takes credit for and apologizes for "stealing" from contemporaries. There is a great deal that we take for granted today in the world of psychology that made its entrance through D.W.W.
