Alex's dream came true.
"I stayed as calm as I could and just drove. I guess all that practice paid off," he said.
Harriet Anne McKinnon arrived at 1.30pm, the day before the couple's one year wedding anniversary.
The proud new father added, "People tell you what to expect, but it's crazy, just crazy."
"At that moment she arrived I had so many thoughts - we were bawling our eyes out."
"It's easily one of the biggest and best days of my life," he told the Herald.
"I’m so happy to see the baby healthy and to see Teigan healthy as well.
"Her performance was incredible. I knew she was amazing before that but for her to do that, it blew me away."
Congratulations to Alex and Teigan!
