A father delivered his own daughter outside a hospital in Dallas, Texas, after his wife was having "big contractions" mere blocks away. Video released by the hospital shows Luis Mendoza helping his wife Angelica Martinez as two dozen hospital staff members rushed in on Sept. 2, before being moved into the delivery room."Dad was the hero of the day," Carrie Urista, a nurse manager at the hospital said. "He had already lifted the baby up and laid her on Mommy's tummy." https://cbsn.ws/4nGjIiF | CBS News
