This is a superb guidebook for parents. As the father of three children (15, 13 and 8) this is the one book that has information pertinent to each--and, actually, to kids of all ages. It is informative in a witty, anecdotal and non-preachy way. I only wish it had been available years ago when the kids were born-- it might have saved me a lot of angst as they were growing-up.
