Sunrise host Natalie Barr disappears halfway through live broadcast: This is the emotional reason for her sudden departure

Sunrise host Natalie Barr surprised viewers when she disappeared in the middle of Channel Seven’s breakfast show on Wednesday morning.

The 55-year-old was co-hosting the show with Matt Shirvington when she revealed she would be leaving early to attend her youngest son Hunter’s final school assembly.

“Today is a big day for me, it’s our last son’s last school reunion, so I’m about to take off,” Natalie told viewers.

“It’s quite emotional and it’s a bit of a milestone. It’s a big day.

Natalie explained that the school would have a “big assembly” and then they would have a nice lunch.

“(It’s a big deal) especially because it’s my last one, so I’m going to take the rest of the show off,” she added.

Last week, Natalie said she became emotional over the impending high school graduation of her youngest son, Hunter.

Speaking to pregnant Miranda Kerr on Sunrise, Natalie told the Australian model to make the most of her four boys’ childhood years.

“It’s my last child’s last day of school today, so I know it’s busy, but make the most of it,” she told the beauty who is expecting her fourth child in Evan Spiegel.

“Because then you’ll cry like I will next week when they have their assembly.”

It came just weeks after Natalie admitted she felt like a “failure” as a mother after giving birth to her first son, Lachlan.

The Sunrise presenter, who shares Lachlan, 22, and Hunter with husband Andrew Thompson, said she felt like a “useless mum” when she couldn’t get her firstborn to sleep when she was baby.

She admitted on the No Filter podcast late last month that she had become “distraught” by the situation.

“I was so distraught because I had a baby who wasn’t sleeping and it was, as many moms know, a helpless feeling,” she told host Mia Freedman.

“My father had just died, I was six months pregnant when my father died, so you think, is that why? Am I still grieving?

Natalie then revealed that a woman in her mother’s group was blaming her for going back to work, claiming that was the reason her baby wasn’t sleeping.

“There’s all this useless information everywhere. You take responsibility for everything, you feel like a useless mum,” the breakfast show host confessed.

Lachlan’s agitation became so bad that Natalie and her husband Andrew, who are notoriously reserved about their children, sought help from a “baby whisperer”.

Natalie then revealed that her second son, Hunter, born four years later, was sleeping much better.
