Purim is just around the corner and, in my house, that means my children have been super-glued into their costumes for about three weeks. My 6-year-old son, a dinosaur fan, has been wearing his T-Rex hat and roaring at the baby non-stop. My 3-year-old daughter has been wearing her poofy, pink princess dress and tiara, alternately calling herself Cinderella or Queen Esther. My daughter in a princess dress is not all that unusual. She has a few “savta bought” (obviously) tutus she loves to twirl around in, but having just read Peggy Orenstein’s “Cinderella Ate My Daughter: Dispatches from the Front Lines of the New Girlie-Girl Culture,” both the Cinderella talk and the Queen Esther talk are giving me pause.
