Jason Kelce had an extra special cheerleader on the sidelines rooting for him on Sunday.

The Philadelphia Eagles center, 35, had his three daughters in the stands at Lincoln Financial Field for the very first time, with wife Kylie Kelce sharing sweet photos from the day on Instagram Monday.

“We were celebrating a 4th birthday when the Birds went 4-0,” she captioned the shots, which showed the family of five posing together, first on their own and later with Jason’s mom, Donna Kelce, and Kylie’s parents, John and Mary McDevitt.

Kylie also revealed the game was “Bennie’s first game (outside of my body),” referencing how she attended games while pregnant with the now 7-month-old.

Another sweet shot in the set shows older daughters Elliotte, 2, and Wyatt, 3, hugging each other tight on the field.

Last Sunday, the mom of three, 31, shared a few photos from daughter Wyatt’s mermaid-themed birthday party, which included vibrant decor such as teal, purple, pink and orange balloons. Kylie reshared a photo of her daughter on her Instagram Story as she played in a giant bubble house, surrounded by multicolored balloons.

“Wouldn’t be a proper mermaid party without a BUBBLE!” read the text on the photo, as Kylie added, “Peep Wyatt 👀 She was in love.”

Another picture showed a giant backdrop of a mermaid, made by Venus & High Volt Co., with the words, “Wyatt Turns Four,” written across the top.

In February, the mom of three spoke to PEOPLE about what she loves most about Jason as a girl dad. “I don’t think in his life, Jason ever assumed that he would be the father of three daughters,” Kylie told PEOPLE at the time.

“He would always be like, ‘No, no, we’ll get a boy. We’ll get a boy.’ And I’m like, ‘You got to stop challenging the universe. Stop saying it because you’re the universe is like, ‘Yeah, okay,’ ” she chuckled.

“I used to tell him before we had our first daughter, she’s gonna have you wrapped around her finger. He said, ‘I’m not gonna spoil her!’ And I’m like, ‘I don’t think you understand.'”
