Landing on her back. From the New York Daily News:
A Manhattan lawyer strapped her 10-month-old son to her chest and leaped to her death from an eighth-story window in Harlem on Wednesday—and the baby miraculously survived with little more than scratches, police sources said. Cynthia Wachenheim, 44, who left a suicide note castigating herself for being a bad mother, landed on her back after taking the fatal plunge. Baby Keston was in a harness. He bounced off his mom on impact and then rolled away from her motionless arms.
Pertinent details: Wachenheim was believed to have been suffering from postpartum depression. Also: “Wachenheim was convinced her baby had cerebral palsy, although doctors said there was nothing wrong with him.”
Full tragic story here.

How disturbing, and sad, with all the respect to her family who is mourning, but I canโt understand why did she took her son along?? definitely an angel saved him.
