On a 2022 episode of "The Culpo Sisters," Olivia Culpo opened up about starting a family with McCaffrey. The model said she always envisioned herself married with kids by the age of 30, but reality isn't aligning with her plan. While McCaffrey does want children at some point, he isn't ready yet. "He is completely and totally focused on football and he should be. He's not ready to have kids. It's not really an option," she said (via People).

Culpo also opened up about her endometriosis diagnosis, which is a condition that can affect fertility. Because of the condition, she wants to have kids sooner rather than later, calling it a "ticking time bomb." "There is so much that I don't know about what's going to happen in the future with that condition and I worry all the time about my timeline," she said. "I feel like I have to have kids ASAP."

The model also expressed concern that putting too much pressure on McCaffrey to have children would affect their relationship. She also couldn't help but compare herself to the people around her. "All of my friends are having babies. ... I'm the odd one out," she said. However, after getting engaged, it seems she wants to wait until after getting married. "I feel like the day after my wedding, I'm just gonna rip out my IUD and start trying immediately," she said on TikTok.
