Preface to the<br > Second Edition<br > The first six chapters of this book， the ones that deal with the<br > changes that are happening in children s bodies during puberty，<br > are quite similar to those in the first edition. I haven t made any<br > major revisions in these chapters because there simply wasn t any<br > reason to do so， and I don t expect there ever will be. No matter<br > how much the times may change， kids will undoubtedly continue<br > to go through the same sequence of physical changes， and have<br > the same questions， concerns， and anxieties about these changes<br > generation after generation.<br > Thus， the major revisions in this new edition come later in the<br >book.
