Married for five years, Garner and Affleck, 39, have daughters Violet, 4, and Seraphina, 2; they confirmed they were expecting again in late August. "So the other day... [Violet] is in there with me and all of the sudden she went, Oh Mom, we have to have a talk...She said, 'Mom, your bottom has gotten so big that your panties don't even begin to cover it."
The Alias actress cleared up the confusion with her eldest: "I said, 'It's called a thong, you wear it when you're a grown up. She was like, 'Uh, that is so gross!"
Meanwhile, Violet and her little sister Seraphina "have a lot of opinions" on their sibling-to-be, Garner says. "They don’t really care about the gender as much as long as we name it what they it to be named."
Some of the cuties' suggestions? "Ralphie, Frankie, Minnie Mouse, Daisy Duck. Rosemarie.. Daisy Duck Affleck. I can see us going that way," Garner cracked, laughing.
As for the Hollywood couple's own hopes for their baby-to-be's gender, "Obviously we'd be happy either way," Garner says. "It would be so weird to have a boy and cool and different. And I'm sure it would be fun for Ben he likes baseball and all that stuff. But a third girl, three girls is a great way to grow up." (Garner herself grew up with two sisters.)
For now, Affleck is content playing not baseball but "baby doll" with his little girls. "My husband plays a lot of baby doll. He is really cute," Garner gushes. "I will walk in and he will be sitting on a little chair. He's so tall! And he'll have a baby doll and I'll say, 'What are you doing?' 'I'm watching Frankie (the baby doll) here."
