Peter Doocy and Hillary Vaughn have welcomed their third child, a daughter named Molly Kate. She was born on October 22, 2026, joining older sister Bridget and brother George. The couple shared the news publicly on November 1, describing their happiness at bringing the newest member of the family home.
The arrival follows a series of family milestones that viewers have heard about alongside the journalists’ television work. Since marrying in 2021, Doocy and Vaughn have welcomed three children, with the latest announcement completing a pregnancy Doocy had discussed on air earlier this year.
The news began with an on-air announcement
Doocy revealed the pregnancy at the end of The Sunday Briefing on May 31. A report of that broadcast records him turning from a segment about younger Americans to his own family, showing images of the two children already at home before sharing that another baby was on the way.
The announcement connected a personal update with a familiar work setting. Doocy also referred to the coming midterm election coverage, placing a major family event alongside an especially busy period for political television. He shared the update while discussing his two older children, making the new pregnancy part of a family story viewers had already heard about.
By November, the anticipated arrival had become a birth announcement. Molly Kate joins a household in which Bridget is the eldest and George is now an older brother as well as a younger sibling.
Their marriage preceded the growing family
Doocy and Vaughn met through their work at Fox. Their relationship history traces the next major public milestone to their wedding in South Carolina in April 2021. They married in Bluffton during the pandemic, before either had become a parent.
Their first child, Bridget, arrived in February 2023. George followed in April 2025, meaning the transition from one child to three has taken place within a few years. Each announcement has added a different family detail to public profiles more commonly associated with reporting and television appearances.
That chronology also explains why the newest arrival changes the siblings’ positions. Bridget has already experienced welcoming a younger child, while George is becoming a big brother for the first time. It is a new stage for the family, even though the parents have navigated the newborn months before.
George’s birth already had a memorable date
George Jack Doocy was born on April 16, 2025, the couple’s fourth wedding anniversary. The announcement of his arrival described a labor lasting around 30 hours after Vaughn had attended a routine appointment. At the time, she spoke about the pleasure of seeing Bridget welcome her baby brother.
Doocy joked that sharing the wedding anniversary would make the date easier to remember. Beneath the joke was a simple family coincidence: a day already associated with the couple became their son’s birthday as well.
The latest announcement adds October 22 to that calendar. Molly Kate’s name and birth date are the central details the couple have made public. Together with Bridget and George’s earlier arrivals, they mark the next step in a family story that has unfolded alongside their broadcasting careers, from colleagues to spouses and now parents of three.
