Josh Dallas and Ginnifer Goodwin's alter-egos in "Once Upon a Time" have no immediate plans to expand their family in the series, but the real-life couple is looking to give baby Oliver a brother or a sister.

In an interview with E! News, he said they want to expand their brood soon.

"Maybe somewhere down the road. We'd like to give this guy a brother or a sister for sure. Close in age would be nice....Have a little buddy," Josh Dallas said.

Speaking about baby Oliver, the "Once Upon a Time" actor couldn't help but gush over his 10-month-old son with Ginnifer Goodwin.

"He's moving and grooving," he said. "He wants to get out and go. He wants to go everywhere."

Josh Dallas also said that he's more protective compared to Ginnifer Goodwin when it comes to baby Oliver "but I think that's probably a good thing."

Although the reel- and real-life couple is not getting much sleep these days, Josh Dallas said that he wouldn't exchange that for the world.

"It's the best! Sleep is elusive but it's all good. He's the greatest person I know and he makes me laugh every day and he keeps me busy," Ginnifer Goodwin's husband said.

For her part, Ginnifer Goodwin told Seth Meyers on his Late Night show, as shared by Daily Mail, that they make it a point to be always involved with baby Oliver's life even if they are busy with "Once Upon a Time."

In order to maximize their time with their little one, the couple brings baby Oliver to the set.

"We have this Star Wars nursery, which is his home away from home. And he was there a lot in the beginning as I was breastfeeding," Ginnifer Goodwin said.

"I'm like forcing [Star Wars] on him ... I think I was kind of meant to be a little boy in some ways so there's a lot of, 'I wish I was an astronaut, so he will be an astronaut."'
