Jeff Bauman, 28, and his fiancée, Erin Hurley, 27, told The Associated Press in a recent interview that the baby is due July 14. They don't know if it's a boy or a girl, and they want it to be a surprise.
"My mom loves it. My dad's going crazy," Bauman said. As for himself, "I just want to be a good dad."
The two have been preparing for the baby's arrival by painting a nursery in their home in Carlisle, Mass. Hurley said Sunday that she and the baby are healthy and her pregnancy is going well.
They got engaged in February and picked out a white-gold engagement ring. She said they plan to marry next year.
"We've got a lot going on. So we don't need to do everything all at once," Hurley said.
An AP photo of a badly injured Bauman being rushed away in a wheelchair by three rescuers became one of the most memorable images of the April 15 bombings, which killed three people.
He was standing near the finish line waiting to cheer on Hurley as she completed the marathon when the two bombs exploded. Bauman became a hero after he provided a description of one of the suspected bombers from his hospital bed.
Bauman's memoir on his experiences, called Stronger, is out April 8, one week before the anniversary of the bombings.
