READ NOWMary-Anne’s sister also has twins.
With all these twins in the family, both nannas agreed they wouldn’t mind a bit of peace for Mother’s Day.
“Or a day off cooking,” Mary-Anne said.
A week long sabbatical, was Julie’s wish.
“Or husbands not getting jealous because it’s not father’s day,” she said.
Mary-Anne, who is also a mother of three, said motherhood required selflessness.
Julie, who is a mother of four, said motherhood means being busy.
“And being absolutely nothing anymore because you belong to every body,” she said.
They both agreed they wouldn’t have their lives any other way though.
Kohen and Lottie were a welcome surprise, after Sage and James tragically lost their infant son Korben to SIDS earlier in the year.
When Alycia announced she was having twins soon after Kohen and Lottie were born, Mary-Anne could not believe it.
“She said we are having twins,” Mary Anne said.
“I said I need proof.”
The proof joined the family about six months later.
