The baby boy was delivered via an emergency c-section.
According to Adam, Raven began having "really bad contractions" on Monday morning. She was taken to the hospital and given an epidural. That night, Adam provided another update, writing, "so far so smooth."
"Epidural is [key]," he wrote. "We are all hanging out watching TV and nurses coming in to check her body position. Raven is an absolute trooper! Soaking it all in."
Several hours later, Adam revealed their son had arrived, though the birth didn't exactly go according to plan.
"Little man made it," Adam wrote alongside a pic of his son's footprints. "Had emergency C-section after pushing for about an hour and a half."
Adam noted that "mom and baby are doing very well," before revealing that the newborn arrived at 3:33 a.m., weighing eight pounds and six ounces, and measuring 21 inches long.
The pair has yet to share a photo of their son or announce his name.
Raven and Adam announced their engagement in June 2019, almost two years after they started dating on season 4 of Bachelor in Paradise. They tied the knot in Dallas, Texas, in April 2021. The pair announced they were expecting just three months later, and revealed it was a baby boy in October.
When ET spoke with Raven in January 2020, she gushed over her then-fiancé, stating, "I love him so much."
