The 54-year-old announced the joyous news on Thursday, February 10, on his Anderson Cooper 360 show.
The journalist also shared the announcement video on Instagram. "Last night I announced the birth of my second son, Sebastian Luke Maisani-Cooper," he captioned the post. "Thank you so much for all the kind messages!"
Anderson first reflected on welcoming his first son, Wyatt, in the "early dark days of the pandemic" in April 2020. He showed baby photos of his eldest son on the screen followed by more recent shots. "He’s nearly 22 months old and sweet and funny and the greatest joy in my life," he gushed.
"If he looks particularly happy in this picture, it’s because he now has a baby brother," Anderson continued before showing the audience a photo of the family's new arrival. "His name is Sebastian and I would like you to meet him — this is Sebastian Luke Maisani-Cooper — he was 6.8 pounds at birth, and he is healthy and happy, even his occasional hiccups are, to me, adorable."
The reporter revealed his new son spends most of his time sleeping and eating. He "certainly poops, but he already seems like a wise and thoughtful little chap," he joked.
Anderson also revealed his "best friend and former partner" Benjamin Maisani is in the process of adopting Wyatt. He explained that his eldest son's last name will be changed to Maisani-Cooper because they are "coparents" to both children.
Anderson took a moment to thank the medical team who helped to bring his new baby into the world. He also thanked Sebastian's surrogate.
Anderson announced he was taking some time off work to focus on his children. He admitted to anchor John Berman that he is much calmer this time around, adding: "He's doing great and he's just so adorable, he's got a lot more hair than Wyatt had when he was born, and he's just incredible."
Wyatt is thrilled about being a big brother, the 60 Minutes correspondent revealed. Wyatt calls his brother "Luke" because he finds it difficult to pronounce Sebastian at such as young age, the proud father explained.
Wrapping up his statement, Anderson asked his loved ones and fans to donate items to local organizations in need rather than sending him gifts for Sebastian.
