Kylie Kelce isn’t ruling out a fourth baby!

The former field hockey player and wife of retired NFL star Jason Kelce, 32, recently hinted that she is open to welcoming a fourth baby with her husband, as she spoke in an interview about saving her daughters’ old pajamas for possible future addition to the family.

“We’re rotating through clothes we bought for our first daughter now to our youngest, so we have gone through a lot of hand-me-downs,” Kylie told New York Magazine website The Strategist of outfits for her three girls Wyatt, 4½, Elliotte, 3, and  Bennett, 15 months.

“… The Hanna Anderson PJs last forever. We still have some packed up, just in case there ends up being a fourth,” the mom of three added. “It is the best investment.”

Kylie also spoke about a favorite item of hers being a Zoe Chicco necklace displaying the initials of her daughters, gifted to her by her husband Jason, 36, “as a reminder of our three greatest creations.”

“He got me the W when Wyatt was born, and I didn’t take it off for four years until I updated it with the other two kids’ initials,” she recalled. “It’s something I wear every single day. It’s part of their Itty Bitty collection and has these tiny initials of our girls on it. I’m really into understated, dainty jewelry over big pieces.”

Kylie’s comments came after she posted a cute photo of her three girls posing together under a rainbow on June 18.

“Parents know… 2 out of 3 isn’t bad! 😐😁😁,” the mom of three wrote at the time, poking fun at the difficulty in getting kids to pose together for photos in her caption.

Ahead of Father’s Day this year, Kylie spoke with PEOPLE about her partnership with HP and the Eagles Autism Foundation on creative, screen free way to keep kids busy over the summer, and opened up about what she and her daughters had planned for Jason for the special day.

“I’m actually doing a project with the girls for Father’s Day so that we can give them gifts that they have made themselves,” she told PEOPLE, adding, “Not to spoil anything, but there’s a lot of rocks at the beach, and our girls are fascinated with rocks. So we’re taking some paints down to the beach today and we will hopefully be decorating rocks for Dad that he can keep as tokens of their love.”
