Travis Kelce revealed a touching moment with his new niece in the documentary ‘Kelce’.

Jason Kelce is teaching his brother the ropes of parenthood.

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 welcomes his brother Travis Kelce, 33, to the family’s newest member.

Travis sits next to his brother on the couch while Jason holds Bennett Llewellyn, his newborn daughter, and coos at his niece when Jason offers to transfer her to him.

“Good ball security,” the older brother says as he passes the infant, who sits in her uncle’s lap.

“Hey, girlie,” he says. “How we doin’?”

“Just like a football,” Jason reminds him as Travis makes her comfy and both brothers smile at the newborn, who is now six months old.

Jason Kelce’s Daughter Slams Travis Kelce for Being ‘Naughty’ and ‘Sneaky’ While wearing her father’s wig

Jason’s wife Kylie spoke with PEOPLE earlier this year about Travis’ participation with the couple’s three daughters — Bennett, Elliotte, 2, and Wyatt, 3 — and praised the Kansas City Chiefs star as the “absolute best” uncle.

“It’s very funny, Jason said in an interview that he thinks [the girls] might like him more than they like Jason,” she said with a laugh.

“He is like the absolute best uncle you can imagine,” Kylie concluded.

“I tell everyone that when he comes to our house to visit, the poor guy does not sit on the couch because our children will say, ‘No, no, you sit on the floor. We’re going to do a puzzle. We’re going to build blocks. We’re going to do this. “We are going to do that.”

Kylie stated that she has tried to convince Travis that he may decline his nieces’ numerous demands.

“Our oldest, she is our boss. She’s our ringleader, and she’s constantly in demand for his services. And I’m like, ‘Trav, do you know you can tell Wyatt no?'”

“He said, ‘Yeah, I don’t think I can.'” “And so he will do it,” she stated.

“She’ll say, ‘Jump up and down.’ He will do it. ‘Roll on the floor,’ he will. ‘Be the Pony.’ He will do it. So he’s fully committed to being an uncle. He is the definition of an uncle, whole and through.”

On a February episode of their podcast, New Heights, the brothers laughed a lot with their mother, Donna Kelce, as they discussed the upcoming Super Bowl, in which both brothers were playing. The brothers teased their mother throughout the conversation, trying to get her to declare which of her two sons she supported.

“You’ve told both of us before that you root for me because I’ve given you grandchildren,” Jason stated during the debate. “I’ve always knew you were rooting for Travis. So, who do you really root for?

Donna cleverly turned the question back on her sons, asking if they’d save her or their father, Ed Kelce, if they were stuck on a boat in the middle of the ocean and could only save one.

Despite repeated attempts to get her to choose who she would support against, she refuses. Jason went on to say, “Remember if you choose me, Wyatt and Elliotte grow up without a father.”

All three laugh, with Travis saying, “I gotta start breeding, I gotta start breeding,” and “To all the breeders out there,” before drifting off in laughter.

“Please don’t,” Jason joked.

“Wait until you find the right person,” Donna said. “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 ended.
