Having one set of twins is a big surprise. But imagine having two sets, just two years apart. That's exactly what happened to Gabby Radlof and her husband, Ben, who defied the odds by having identical twin sons, Hugo and Spencer, in 2018, followed by fraternal twins, Billy and Aria, in 2021.
Gabby spoke to Mamamia about the many things people don't realise about having twins, starting with the cost.
"Budgeting for the twins' nursery came as a bit of a shock!" Gabby said. "We had to get two of everything and there is no extra financial support. I didn't know that the Australian government does not consider twins as a 'multiple birth', which is crazy!
"Thankfully, when we found out that we were having a second set of twins, we had kept all of Hugo and Spencer's things, so we got to reuse the nursery items."
But knowing what to do with their family car the second time around wasn't quite as straightforward.

"With our second set of twins, car seats and safety harnesses were a real issue. I wasn't working and we couldn't afford a new car so we paid to have additional anchor points fitted in our Kluger. It was still expensive but a lot less than a whole new car!"
