It’s been a week since the birth of his new daughter Gia and what is Matt Damon doing when he’s not on diaper duty?

He’s working his thumbs to the bone to keep his old buddy Ben Affleck up to date on all of the details.

“I’ve kind of been texting him back and forth, and he’s doing great and [wife] Lucy is doing great,” Affleck, 36, told PEOPLE on Wednesday at the Democratic National Convention.

Affleck is in Denver supporting a variety of political and charitable causes, including playing poker on Tuesday with the likes of Sarah Silverman – on behalf of paralyzed veterans.

Still, Affleck’s mind was not far from his old Cambridge pal, who is fast becoming odd man out in his Miami home, what with the addition of little Gia to his strictly female brood of wife Luciana and their daughters Isabella, 2, and Alexia, 10.

Not that Damon – PEOPLE’s Sexiest Man Alive – has any problem with that.

“Anybody who has a child is excited, I think, no matter what the gender is. They are thrilled,” says Affleck. “The thing that people really want, when you get down to it, is a healthy child.”
