The Jonas Brothers -- Kevin, Nick and Joe -- are opening up about the "unspoken rule' in their family that helps them all get along as the fathers of five daughters combined.
The brothers' not only all have daughters, but their kids are also fairly close in age.
Nick Jonas, 30, shares his 14-month-old daughter with wife Priyanka Chopra Jonas.
Joe Jonas, 33, and his wife Sophie Turner share two daughters, born in 2020 and 2022.
Kevin Jonas, 35, and his wife Danielle are also the parents of two daughters, born in 2014 and 2016.
The brothers make it all work, they say, by not sharing tips or feedback on being dads.
"We really don't give each other advice about family. It's kind of like an unspoken rule," Kevin Jonas said in a SiriusXM interview this week, alongside his brothers. "We just do our own thing."
Nick Jonas explained further, saying, "As we become parents too, we basically just set up a rule that was 'no feedback, no advice.' You go on your journey, do your thing. I'm going to do mine. And it's like the healthiest way forward."
"The last thing you want to hear from your siblings is how to parent your child," he continued. "I think we all sort of understand that and just say, 'You do your thing. I'm just gonna show up and be Uncle Nick,' and that's how it goes."
Rachel Simmons, an author and parenting expert, said that the Jonas siblings are smart to take a proactive approach to helping avoid conflict.
She noted that unsolicited advice from siblings can be particularly hard to handle.
"When somebody criticizes your parenting, it is so hard not to take it personally," Simmons told "Good Morning America." "And when that is coming from a sibling that you have a history with of all kinds of arguments, it's almost impossible not to have that turn into a conflict."
Simmons noted that unsolicited parenting advice can come from not only family members, including grandparents, but also friends.
To help cope with the unsolicited advice, Simmons advises people to take a four-step approach:
1. Appreciate their concern.
2. Thank them respectfully.
3. Set boundaries.
4. Drop hints that you are comfortable with your parenting style.
Simmons said it's also best for parents to tune the advice out and focus on their kids.

"We really just have to acknowledge that there are as many different ways to raise kids as there are kids," Simmons said. "It's not our job to parent other peoples' kids. It's our job to parent our own children."
