The four professional dancers had a fun trip as they enjoyed family time in Utah

Peta Murgatroyd and Jenna Johnson are having fun getting in some quality time with their little boys.

The pro dancers, who are sisters-in-law, enjoyed a Chmerkovskiy family trip to Park City alongside their husbands, Maks and Val Chmerkovskiy.

In one photo from the trip shared by Peta and Maks on Instagram, Peta and Jenna share a fun moment together as they each hold their baby boys. Peta's son Rio, 6 months, and Jenna's son Rome — who celebrates his first birthday on Wednesday — gaze at something out of the frame as their moms share a laugh.

In addition to Rio, Peta and Maks also share son Shai, 7. The couple chatted with PEOPLE in the fall, opening up about their recent social media pivot toward humorous family content.

Chmerkovskiy, 43, said the videos play into their sense of humor. "We are that couple and some of these things, well most of them, really reflect us," he laughed.

"Shai loves it," Murgatroyd, 37, added. "He's like, 'When are we doing another one? Can I be on camera?' He's so funny."

"And we don't push him to do any of this stuff. If it's not a good day or he doesn't want to do it, he doesn't be a part of it. I think I'm the mastermind behind it, but we made a decision like, 'Hey, let's just do these funny videos.' They make us laugh. We enjoy creating them."

Last year, Maks opened up to PEOPLE about how special it is to give Shai a sibling after he and Murgatroyd dealt with fertility struggles.

"He knew the story kept being that mommy has an egg, and then the egg broke. So finally, at this point, to tell him this egg didn't break, it's a very big moment for him and for us, seeing that baby come," he said.

"Now there's kicking, the stomach is moving. Watching [Shai] taking in that moment is also very special."
