Nine presenter Sylvia Jeffreys shares a sweet picture of her newborn son Henry

Sylvia Jeffreys and her husband, Sky News anchor Peter Stefanovic, welcomed their second son, Henry, last month.

And the Channel Nine presenter, 35, revealed on Thursday she was adjusting to the ‘highs and lows’ of being a mother of two.

The newsreader shared a relatable post on Instagram about her newborn interrupting her usual sleeping pattern.

‘Keeps me up all night. Cranks up the cute factor in the morning. The highs and lows,’ she captioned a sweet photo of the little boy. 

Sylvia and Peter announced the arrival of their second child on April 7.

At the time, she shared photos of the baby on Instagram, and wrote: ‘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.’

Peter also shared the news on his social media, writing: ‘The newest littlest member of our squad of four, led by my hero – @sylviajeffreys.’ 

The couple began dating in 2013 after meeting at Nine and were engaged in 2016 while on holiday in France.

They tied the knot at the Ooralba Estate in Kangaroo Valley on April 1, 2017. 

Last year, Sylvia and Peter welcomed their first son, Oscar Hamilton, who turned one in February. 

Just eight months later, the Today Extra host revealed she was pregnant with her second child, another son.

Sylvia conceived her first son, Oscar, via IVF, but said her second pregnancy was ‘spontaneous’.

‘We hadn’t planned to go down that path so soon, but having had not an entirely easy path the first time around you can’t be anything but thankful and grateful to have fallen pregnant this way,’ she told The Australian Women’s Weekly.

She said many people had advised her against having boys 15 months apart, but she insisted they wouldn’t have it any other way.

‘I know it will be a lot to keep up with two turbo little boys, but for now I’m just embracing the beautiful chaos,’ Sylvia added.
