The happy baby news comes after Edwina announced her pregnancy in August 2021 with a tongue-in-cheek Sunrise segment.
"In developing news, news that will be developing news, news that will be developing for the next six months, we will be having another baby," she said.
"Due in February, and I tried to tell Molly and she was not terribly interested. I showed her the photo and she scrunched it up and threw it on the floor."
The host also revealed she knew the gender ahead of the birth, but didn't want to share the news with the public.
“We found out this time because we just wanted to know, but I wanted to keep that one as a little secret,” Edwina told her co-hosts, David Koch and Natalie Barr.
Edwina has been open with fans about all the challenging moments that come with motherhood, but she's also keen to celebrate the positives too.
"I think it's so rare for women to say, 'Hey, I'm good at this,'" she told our sister site TV WEEK, referring to the pressure women face as new mothers.
"But you know what? I'm a really good mum, and Molly's a really good baby. And we have a really happy family.
"That's such a huge achievement. I don't think 'old me' would have recognised that it's a big deal and a great thing to be able to accomplish."
