Alex and Teigan McKinnon have shared a memorable week with their three daughters as they've rung in two significant milestones back-to-back.
On October 8, the besotted couple celebrate their fourth wedding anniversary, and they're clearly as in love as ever.
Alex took to his Instagram first to commemorate his wife and their union by posting a family photo.
The gorgeous black and white image hilariously featured his oldest child Harriet poking his nose while Teigan smiled at their shenanigans with their twins in her arms.
He captioned the moment, "✌🏻✌🏻Wedding Anniversary 🤍."
On his wife's Instagram, she excitedly shared a glimpse inside their wedding day by posting a video filled with highlights from the event.
"FOUR YEARS, Happy Anniversary Hubby!" she wrote.
Her comment section quickly filled with loving messages to congratulate the teacher.
One fan wrote, "Such a gorgeous couple!!! Xx," and another commented, "You two are so special. The love is palpable. Happy anniversary x."
On Thursday the McKinnon family spent the day celebrating Harriet, who turned three, and her mum can't believe how fast she has grown up.
Teigan shared a video on Instagram of her daughter from over the years, and she even included a glimpse inside her third birthday party.
"I'm not sure how that happened or where the time has gone, but this morning we woke up, and we have a three-year-old amongst us!," Teigan began her message.
In the rest of her tribute, she wrote about her daughter's precocious and bubbly personality.
"Happy birthday to our ray of sunshine, our determined, stubborn, chatty, too clever baby girl! We love you more than you'll ever know ❤️," she finished.
Teigan's fans were excited to see the family footage as they have proudly watched them grow over the years.
Under the post one person shared, "Happy 3rd birthday Harriet. You are the best big sister. 🥳🎂💞🎈🎉," and another celebrated by writing, "Very cute."
The adorable couple has been together since they met at a pub through mutual friends in 2010.
However in 2014 tragedy struck when Newcastle Knights NRL player Alex fractured his C4 and C5 vertebrae.
In 2017 they finally wed in the Hunter Valley, and in 2018 Teigan gave birth to their first daughter Harriet.
The couple also shares twin baby girls Audrey Jill and Violet John, who they welcomed into their young family this year in April.
