The new mum first announced her pregnancy on air back in June.
“The girls already know but Kochie, surprise, we’re having a baby,” she said.
Edwina and Neil wed in April 2018 and were at odds on whether to learn the baby's gender, eventually opting to keep it a secret.
Molly is the couple's first child.
Edwina made her pregnancy announcement live on air in June.
"I have a bit of an announcement myself!" a beaming Edwina told her delighted co-hosts on-air at the time.
"The girls already know, but Kochie surprise..." and before she even gets the words out Kochie screams and goes in for a big hug.
Through all the happy squeals of delight from Kochie, Edwina says: "We're having a baby!"
