Wunder Muther, Trendy Ma, Dancing Daddy-boy . . . everyday my post-office box fills with “cool parenting” books and magazines put out by mainstream publishers. They are memoirs and how-to-be-as-cool-as-me tomes; advice journals and fashion rags. Last month a radio interviewer congratulated me for starting this whole “movement” with my zine, Hip Mama. So, how come my reaction to seeing another pile of parenting lit is to roll my eyes? These parents need to grow up, I think.
