Dax Shepard is already thinking about his grandchildren. During this week's episode of the Armchair Expert podcast, the host opened up about his youngest daughter Delta, 11, already looking forward to having children: "She's saying she wants to have a baby, and I said, 'When do you think you'll have your first child? When you turn 18?' I want to be supportive of whatever, I don't want to plant any seeds that I'd be judgmental or whatever.
