Book excerpt: A comic and heartwarming memoir about childhood's second act from Real Simple journalist Catherine Newman. Much is written about a child's infancy and toddler years, which is good since children will never remember it themselves. It is ages 4-14 that make up the second act, as Catherine Newman puts it in this delightfully candid, outlandishly funny new memoir about the years that "your children will remember as childhood." Following Newman's son and daughter as they blossom from preschoolers into teenagers, Catastrophic Happiness is about the bittersweet joy of raising children -- and the ever-evolving landscape of issues parents traverse. In a laugh out-loud, heart-wrenching, relatable voice, Newman narrates events as momentous as grief and as quietly moving as the moonlit face of a sleeping child. From tantrums and friendship to fear and even sex, Newman's fresh take will appeal to any parent riding this same roller coaster of laughter and heartbreak.
