Book excerpt: Parents are a particularly wonderful breed of humans. We are the men and women who cannot sleep at night when we are worried about our children. We are the mothers who go through the greatest pain of our lives and immediately afterward feel nothing but pure joy and gratitude for what that pain has brought. We are the people who would give up everything we have in exchange for our child, who feel more love looking into those beautiful little faces than we have ever felt, who know that there is really no such thing as quality time--it is all quality time. It is for these wonderful people this book is written.
