This is the first time Sylvia has posted a photo of herself since sharing the news of her pregnancy.
“When you find out you’re getting a best bud for life,” she wrote alongside a snap of Pete and her first-born on Friday.
“Oscar’s little brother due in April next year. We are so lucky. 💫💫💫 @peter_stefanovic.”
Many of the couples’ famous friends have expressed their excitement, especially considering the journalist has been open about her fertility struggles in the past.
“😍😍😍 Beautiful news. Congratulations @sylviajeffreys @peter_stefanovic,” model and fellow second-time mum-to-be Jesinta Franklin commented.
“Awww congratulations you guys! This is such wonderful news!!! So happy for you 💙💙💙” added Nine Network reporter Natalia Cooper.
Meanwhile, Sylvia’s former co-host, Lisa Wilkinson, penned an entire post on her friend’s baby joy.
“So happy for my gorgeous friend @sylviajeffreys with the news that she and that handsome devil of a husband of hers @peter_stefanovic are adding bub number two to their beautiful brood. Congrats guys. Xx😘,” she wrote.
Just last week, Sylvia broke down on live television as she discussed her journey to conceive one-year-old Oscar.
Speaking to a guest of the show, Brooke Campbell, she admitted that the IVF process was “daunting and overwhelming” and discussed the options available to families once they no longer have use for their embryos.
“I know from my personal experience with IVF that so much goes into having a successful embryo,” she said, on the verge of tears.
“Having something sitting there that gives you the opportunity to make life for your family. How are you and your husband coping?”
Later in the segment, Sylvia added: “It’s such a fascinating topic, and Brooke obviously something so raw for you right now, so thank you very much for sharing.”
“The silver lining in having unused embryos is that you’ve had your miracles. You’ve had your babies. So that’s the beautiful part of it.”
