Rosanna Davison has shared five things she and her husband Wes Quirke have learned about having three babies under the age of two.
The couple welcomed their "miracle" twin boys just over a fortnight ago, less than a year since their daughter Sophia was born by gestational surrogacy.
Rosanna suffered 14 miscarriages before having Sophia, and attributes her twin pregnancy with Hugo and Oscar to slowing down due to the pandemic.
Taking to Instagram, the model said she wanted to share five things she and her husband have learned "just for fun".
Posting a picture of herself cuddling one of her baby boys, she wrote: "Just for fun, here are five things we've learnt so far from going from having none to one to three babies in the space of less than a year.
"1. As parents, we're a whole lot more relaxed this time around. When Sophia arrived, we barely knew how to change a nappy. Now we pretty much do it in the dark multiple times a night.
"2. Routine is key if you ever want to have the time to actually finish a hot cup of coffee and get that precious caffeine into your bloodstream.
"3. We still discuss who had a nappy explosion and when, but we chat about other stuff too, like which baby did a projectile wee on us and when.
"4. We reminisce much more about those heady days when we used to leave the house together on dinner dates and wonder when it might happen again. Could be two years, could be 10 years. Who knows?
"5. As a newborn, Sophia also taught us, you can live on four hours sleep a night and somehow not die."
To announce the birth of her identical twin boys on November 18, Rosanna (36) shared a snap of herself, Wes and the new arrivals.
"Our beautiful and healthy identical twin baby boys, Hugo and Oscar, arrived safely into the world this morning and our hearts are bursting with love,2 she wrote.
"Just like that, we've become a family of five and all our dreams have come true. We're deeply grateful to the wonderful, hardworking team a @nationalmaternity- hospital for all of their kindness and support."
Hugo and Oscar were dubbed "miracle twins" as Rosanna and Wes had struggled to conceive.
The couple endured the loss of 14 early pregnancies on their journey to become parents, due to the former Miss World having a suspected autoimmune system issue.
In an interview on the Late Late Show last year, she said it was a "lonely, traumatic experience. I couldn't do what my body was biologically designed to do - reproduce".
