pregnancy as she prepared

newly-minted family of five celebrated daughter Elliotte Ray’s second birthday, as Kylie shared on Instagram Monday.

Wishing a joyful birthday to Elliotte, daughter of Jason Kelce! Today, Jason Kelce celebrates his daughter and lovingly describes her as his precious jewel."

“A few days late, but Elliotte is officially 2!” Kylie captioned a set of pictures, which show the toddler smiling in a floral nightgown and winter beanie, standing and smiling in her crib and later in a store with her mom and big sister Wyatt, 3.

In a video shared, Kylie and her daughters were strolling around the store when the toddler spotted a t-shirt with the Philadelphia Eagles center’s face on it and pointed, saying, “dada” and “daddy” sweetly. The mom of three, 30, also shared a photo on her Instagram Story of her homemade Bluey cake for the birthday girl.

“I said that as long as Ellie looked at this and said ‘It’s Bluey,’ that it would be a success,” she wrote. “When I asked her who was on the cake, she shrugged and said, ‘a bunny?’ ”

Speaking with PEOPLE 38 weeks into her pregnancy as she prepared to see her husband compete in Super Bowl LVII, Kylie opened up about what she loves 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.
