Ava Pearl Greisberg

July 26, 2006 12:32 p.m. 7 pounds, 9 ounces New York Presbyterian Hospital Send over the velour sweat suits, size super-small! Sara Greisberg, sales manager at Juicy Couture, has welcomed a fair-skinned little fashionista who enjoys listening to Frank Sinatra and Elvis and staring at the world with her big blue eyes. “She’s a deep thinker,” said the new mom, 32. “An old soul.” Dad is Scott Greisberg, 31, a psychologist based in Ardsley. The couple moved to Larchmont from a Hell’s Kitchen one-bedroom (a decision they’re already beginning to rue). Brought on by a brisk power walk, the agony of labor was eased by an epidural. “The pain is so excruciating that when you don’t feel it anymore, it’s like you won the lottery,” Ms. Greisberg said.
