"March 25, 2021. Celebrating the two loves of my life. Happy first wedding anniversary to my sweetheart husband and day of birth to our beautiful daughter. ❤️ Grace Warrior Irwin Powell. Our graceful warrior is the most beautiful light. Grace is named after my great-grandmother, and relatives in Chandler's family dating back to the 1700s," Irwin explained in her heartfelt caption.
The mom of one continued, "Her middle names, Warrior Irwin, are a tribute to my dad and his legacy as the most incredible Wildlife Warrior.

She chose the perfect day to be born and we feel tremendously blessed."
On his own Instagram page, Powell posted the same photos, writing a sweet caption about welcoming his daughter into the world.
"Grace Warrior Irwin Powell. After waiting for you to arrive for the last 9 months, finally meeting you has been the best moment of my life," he wrote.
