Proud mum Bec also shared a rare snap of all four of her children who she shares with husband, Chris Judd.
In the snap, nine-year-old Oscar, six-year-old Billie and four-year-old twins Tom and Darcy pose in their best Christmas hats as they head off for their final day of school for the year.
"Sending off x4 happy Judds for the last day of school. So proud of them and their amazing teachers for taking 2020 in their stride and thriving, despite 2 terms of virtual learning," she captioned the snap, before sending special shout outs to four specific teachers.
"Can't beat family," one fan commented on the festive snap.
"Go Judds!" penned another.
Speaking on her radio show the 3PM Pick-Up in 2017, Bec opened up her "horrific" birth experience when the twins came along.
“It’s horrific compared to having a natural delivery,” she shared on the air.
“It kills, it absolutely kills. The fact that you are awake in major abdominal surgery is mind boggling and freaky.”
She added: “I remember I was lying there on the operating table and I started pretty much having a panic attack, my heart was going nutso – I felt like it was jumping out of my chest."
“And I think ‘Am I going to die? What’s going on?’ which actually was completely normal.”
Bec has spoken candidly about her "completely different pregnancies" and her "four very different children."
"Watching Hollywood movies you think that as soon as your baby comes out you're going to be in love and crying happy tears with an overwhelming feeling of love and adoration but when my son, Oscar, came out I remember my obstetrician saying, 'Take YOUR baby' and I thought, 'Oh s**t he's mine'," she said.
"And then I got him, I looked at him and I didn't get all of those feelings. I got pretty much complete shock. And I thought, 'Hang on, isn’t this supposed to be the best moment of my life?' And it wasn't.
"I looked at my husband hoping to see the tears and happiness in his face and his face pretty much mirrored mine – he was in shock too. I thought something was wrong with me – the feelings definitely came but it wasn't instant."
