Travis Kelce shared a sweet moment with his new niece in the documentary 'Kelce'
Jason Kelce is showing his brother the ropes of parenting.
In a scene from the Amazon Prime Video documentary Kelce — which follows the Philadelphia Eagles center, 35, through the 2022-2023 season as he makes family and career decisions — Jason introduces brother Travis Kelce, 33, to the newest member of the family.
Travis sits next to his brother on the couch as Jason holds his newborn daughter, Bennett Llewellyn, cooing at his niece when Jason offers to pass her to him.
"Good ball security," the older brother instructs as he passes the baby, who settles into her uncle's lap.
"Hey girlie," he says. "How we doin'?"
"Just like a football," Jason reminds him as Travis gets her comfortable and both brothers smile at the infant, now 6 months old.

Jason's wife Kylie opened up to PEOPLE about Travis' involvement with the couple's three girls — Bennett, Elliotte, 2, and Wyatt, 3 — earlier this year, praising the Kansas City Chiefs star as the "absolute best" as an uncle.
"It's very funny, Jason said in an interview that he thinks [the girls] might like him more than they like Jason," she laughed.
"He is like the absolute best uncle you can imagine," Kylie continued.
"I tell everybody, he comes to our house to visit and the poor guy doesn't sit on the couch because our daughters will be like, 'No, no, you sit on the floor. We're gonna do a puzzle. We're gonna build blocks. We're gonna do this. We're gonna do that.' "
Kylie said she's tried to tell Travis that he can turn down his nieces' many requests.
"Our oldest, she's our boss. She's our ring leader, and she just has demand after demand for him. And I'm like, 'Trav, you know you can tell Wyatt no?' "
"He was like 'Yeah, I don't think I can.' And so he will do it," she said.
"She'll be like, 'Jump up and down.' He'll do it. 'Roll on the floor,' he'll do it. 'Be the pony.' He'll do it. So he's all-in when it comes to being an uncle. He is the epitome of an uncle, just through and through."
On a February episode of their podcast, New Heights, the brothers shared a lot of laughs with mom Donna Kelce as they talked about the then-upcoming Super Bowl, in which both brothers were playing. The brothers teased their mom throughout the chat, trying to get her to admit which of her two sons she was rooting for.
"You've said in the past to both of us that you root for me because I've given you grandkids," Jason said in the discussion. "I've always known that you root for Travis. So who do you actually root for?"
Donna expertly turned the question back around on her sons, asking whether they'd save her or their father, Ed Kelce, if both were stranded on a boat in the middle of the ocean and they could only save one.
Trying to coax her to make a choice about who she'd root against, she doesn't relent. Jason then noted, "Remember if you choose me, Wyatt and Elliotte grow up without a father."
All three laugh, with Travis then adding, "I gotta start breeding, I gotta start breeding," adding, "To all the breeders out there," before trailing off in laughter.
"Please don't," Jason joked.
"Wait until you find the right person," Donna urged. "Find the right person."
"I'm gonna find a breeder, and I'm gonna get kids so that mom can love me again," the Kansas City Chiefs tight end concluded.
