The youngest son of newly sworn-in California Gov. Gavin Newsom (D) had a viral moment on Monday when he interrupted his father's inaugural address.

Video posted online shows Newsom speaking at the lectern as his son, Dutch, approaches him with a pacifier in his mouth while carrying a blanket.

"We Californians know how much a house matters, and children matter," Newsom said as he picked up his son, who turns 3 next month. 

He continued speaking about his vision for the state of California as his son nestled his head onto his shoulder. 

The San Francisco Chronicle noted that Newsom was accompanied by his wife, Jennifer Siebel Newsom, and their four children while he took the oath of office. 

"My wife Jennifer and I have four children, and there's nothing more important — I hope you can tell — than giving them a good and happy life. But all kids, not just the children of a governor and a filmmaker, should have a good life in California," Newsom said during his speech. 

Newsom, formerly California’s lieutenant governor, won the race to succeed Gov. Jerry Brown (D) in November. 

The former mayor of San Francisco campaigned on working towards a universal preschool and a single-payer healthcare system.
