MILWAUKEE, WI (WTAQ) - A one-month-old girl has become the second baby to die in a sleep-related mishap in Milwaukee in 2012. A medical examiner's report said Lilly Grundle suffocated in bed with her mother -- and the death has been ruled an accident. Authorities said the girl's mother was breast-feeding her in bed when she fell asleep. When her father came home, officials said the child was unresponsive. Lilly was taken to a hnospital where she was resuscitated. But she developed seizures, and she died on February fourth.
