The TV star and her husband, Brian Fichera, welcomed Calvin on Saturday, Dec. 17. The couple — who married in 2012 — previously announced they were expecting their first child together last June.

"Arriving right on schedule in a snowstorm… the love our lives is finally here. Meet Calvin Bradley Fichera: 11:52 a.m., 8.3 pounds, 20.5 inches long. And by the way, childbirth is no joke!! OUCH!!" Dylan captioned a series of Instagram photos of her precious newborn following his birth.

Just one day later, Dylan recounted Calvin's birth during a live video chat with her co-workers on Today. “I pushed for about three hours, and he was a big guy and he didn’t quite fit, so he got stuck,” she said.

“We ended up doing a C-section anyway," Dylan continued. "Childbirth is a lot harder than I ever thought it was going to be. He is just so precious and is so wonderful."

Days earlier, Dylan's Today co-star Savannah Guthrie, 45, welcomed her second child, a baby boy named Charley, with her husband, Michael Feldman.
