Now that Mother’s Day has come and gone, yummy mummies can start prepping for more effective parenting this year. If raising the next president, platinum artist or Academy Award-winning director is on your agenda, then look no further than Stephanie Hirsch’s latest book. The multitalented Inca designer and mother of Hunter recently released Mother Nurture: Life Lessons from the Mothers of America’s Best and Brightest, which includes interviews with the maternal forces in the lives of Beyoncé, Steven Spielberg, Colin Cowie, John Legend, Justin Timberlake, Cindy Crawford and more. On Thursday evening, DKNY and Divalysscious Moms hosted a party to celebrate the tome’s launch. Nina Garcia, Scoop’s Stefani Greenfield (whose mom dishes plenty) Alison Brod and Bethenny Frankel enjoyed the ladies’ night out of shopping, cocktails and an open exchange of parenting tips, preschool admissions nightmares and kid-friendly organic grub.
