David Boreanaz Staying Home – Just in Case
08/19/2009 AT 08:05 AM EDT
"Jaime's pregnant, we're doing construction at the house, and I'm just pulling my hair out," Boreanaz, 40, tells PEOPLE. He and Bergman, wed since 2001, already have a 7-year-old son, Jaden Rayne.
Now there's the new arrival – a girl – to consider. With Bergman on bedrest for the majority of the pregnancy, Boreanaz felt more comfortable staying near.
"I didn't go to Comic-Con because the baby was going to come at any minute," says the anxious father. "We're just waiting and waiting. It's nerve wracking, extremely, [but] I finally just decided that it's going to come when it's going to come."
In the meantime, "I must maintain a 20-mile radius. I cannot travel beyond that. If I do, I'll freak out – I have to be there when the baby comes."
Bergman is due Sept. 1.
