Ringside Dad Moments
After Conor Jr. arrived, McGregor told RTÉ’s The Late Late Show:
> “I’m very proud and very blessed… the birth of my son has made me softer where I need to soften up.”
He’s since carted the kids to media events, including the 2017 Mayweather fight build-up when Junior was weeks old, and runs with them on Dubai beaches, captioning a 2023 clip:
> “Sunday in the sunshine with my kids, thank you God.”
Growing Up McGregor

- Conor Jr. already hits pads at the boxing club where the fighter began; coach Paul Sutcliffe calls him “a natural… no fear.”
- Croía celebrated her 5th birthday with a mermaid-themed party posted January 2024; dad calls her his “real life Princess.”
- Rían rarely appears, but February 2024 saw McGregor post: “Hand on heart… I love you so much.”
- Mack, the newest arrival, stars in sleepy cuddle shots captioned simply: “#LuckyMcGregor.”
Key Takeaways
- Four kids in seven years keep McGregor busy between training camps.
- Instagram serves as the family scrapbook, with Dee’s pregnancies and birthdays shared in real time.
- The fighter’s softer side emerges in every caption: gratitude, pride, and wonder at fatherhood.
From Octagon to bedtime stories, McGregor’s toughest opponents are four small voices yelling “Dad!”-and he wouldn’t have it any other way.
