Congratulations are in order for Fifi Box, who is expecting her second baby!
The 41-year-old took to her Instagram to share the very special news via an adorable video featuring her daughter, Beatrix 'Trixie' Belle, 5.
Next to the video was a caption explaining that the new addition had been conceived via IVF and an anonymous donor.
"We're having a baby!!" she captioned the post. "Yes Trixie and I are over the moon/jumping out of our skin/can't stop smiling/floating on air/dancing in the streets/walking on sunshine and every other metephor that conveys absolute pure joy 😍 How did this happen you might ask?"
"Well, a few years ago I made an appointment to see an IVF specialist, the amazing Dr Sameer Jatkar at Monash IVF, and I began an IVF journey to extend our little family.
"After a series of egg retrievals and freezing, last year I started the process to become pregnant via an anonymous donor."
Fifi continued: "I am still pinching myself that I have been this blessed and that this little miracle is growing within me, a much wanted and longed for sibling for a very excited big sister!
"I know the value of this miracle because I have seen first hand the heartbreak, tears and sacrifices so many women and couples suffer on their IVF journeys and my heart goes out to those who are facing that pain and struggle.
"It is not lost on me that I am one of the lucky ones. Being a mum is my greatest joy in life, it is quite simply everything to me.
"Trixie has brought me more happiness and love than I ever imagined possible and to feel my heart expanding to include this little angel kicking and rollicking within me, I am overwhelmed with how much love and happiness the future holds. I will cherish Trixie and this little angel forever, and hold them so close for the rest of our lives 💕💕💕 #family"
On Thursday, Fifi shared some emotional snaps of her and Trixie, whom she shares with former Ironman Grant Kenny, on her very first day at school.
To kick off the emotion-fuelled 24 hours, Fifi posted several pics of the mother and daughter duo sharing some sweet moments together over the years, writing: "The night before my baby starts prep tomorrow and I have gone totally emo! How did this happen! She was just born 😭😭"
Then, on Thursday morning came the big moment - a picture of Trixie looking absolutely adorable in her new school uniform complete with backpack and hat.
"This happened today 😭😭😭," wrote Fifi.
Congratulations to Fifi and Trixie on their fabulous news!
