Matt Lauer, Wife Welcome A Boy
"The baby was born this morning at 9:37 a.m. in New York City. He weighed 7 lbs., 4 oz.," Today spokesperson Megan Kopf tells PEOPLE. "Mom, Dad and baby are all doing well."
The baby's unusual name (pronounced "Tice") is a common Dutch name. "Annette is Dutch and in following with her heritage, the baby was given a Dutch name," says a source.
This is the third child for the Today anchor, 48, and his wife, 41. Thijs joins brother Jack, 5, and sister Romy, 3.
Lester Holt filled in for Lauer on the NBC morning show on Tuesday.
Lauer revealed that he and Annette were expecting in August in an interview with the Sunday New York Times magazine.
"I was on Today for five years before I had children," he said in the interview. "And back then the job took up a larger slice of the pie graph of my life than was healthy. When I had kids, that immediately changed. It flipped."
