The book seems to be based on close observations of thousands of families, by someone with good judgment. It says what the child should be doing at a given age, and what you the parent should be doing, without euphemisms or ideology. A big theme of the book is that you must establish compliance with rules between the ages of 16 and 24 months. I began to read this book just *after* my child turned two, and it is a bit sobering for me to ponder how sound its observations and advice appear now. I own at least two or three other books on parenting (the also good Brazelton and the treacly Dr. Sears), and this one is easily the best.
