"He works from home, and so he gets to be with her as much as I do. Well, not as much, because he's working all day long, but he actually gets to come out of a meeting and give her a kiss and play with her for a little bit, where if he was going to the office every day he wouldn't be able to do that." "We're just having a lot of gratitude for that," Diaz said. "And yeah, it's pretty wild."
