She welcomed her second son Henry with husband Peter Stefanovic earlier in the month and now their newborn bub is meeting a very important family member.
Sylvia Jefferys' lookalike sister Claire Going recently jetted to Sydney from interstate to help out with the new bundle and the Today Extra star says she couldn't be more grateful for her support.
Taking to Instagram to praise her sibling, the TV star wrote: "She came, she cuddled, she batch-cooked. We love you, Aunty Claire @cfgoing."
The sweet post was accompanied with a black-and-white photo of Claire holding Henry alongside Sylvia.
Clearly smitten with her new nephew, Claire commented under the pic: "...and she loved every minute! Thanks for having me xxx."
The Project host Lisa Wilkinson shared her support for the sisters in the comment section, writing: "Some excellent sistering and snuggling going on in that pic! ❤️❤️❤️ xx."
Meanwhile Australian journalist Jodie Speers also commented on the sweet pic: "Naw, the magic of a sister! Hope my girls do this for each other one day! x."
The extra set of hands would no doubt be a huge help for the new family-of-four as they navigate life with two boys under two.
Peter and Sylvia, who tied the knot in 2017, announced their second son's birth on April 7 with a selection of touching newborn photos.
"Henry Our gorgeous, healthy little boy makes us a family of four. His proud parents couldn't be happier. His big brother is learning to be gentle. Big love all around," Sylvia penned.
They are also the proud parents to one-year-old son Oscar.
Today Extra star Sylvia, 34, announced she was pregnant with her "miracle" second son in October last year.
"When you found out you're getting a best bud for life. Oscar's little brother due in April next year. We are so lucky," Sylvia captioned a sweet snap of Pete, 38, holding baby Oscar.
The couple have been open about their struggle to conceive their first child through IVF so despite their initial shock at falling pregnant naturally just eight months after giving birth to Oscar, it was a much welcome blessing.
"The second time around it was… spontaneous I'd say," Sylvia recently told the Australian Women's Weekly.
