America Ferrera took to Instagram today, May 29, to announced that she and husband Ryan Piers Williams recently welcomed her first child, a baby boy named Sebastian Piers Williams.

“When 2 become 3,” the new mom wrote along with a pic of her newborn’s foot and what appears to be one of her hands and one of her husband’s. “Welcome Sebastian Piers Williams — AKA Baz! Mom, Dad, and Baby are happy, healthy, and totally in love!”

The couple first revealed on New Year’s Eve that they were expecting their first child. Ferrera posted a pic of herself and Williams wearing festive glasses and holding up a tiny onesie that said, “More kisses (please),” in Spanish. “We’re welcoming one more face to kiss in 2018!” she captioned the photo. “Wishing you #MásBesos in the New Year! #babybesos #HappyNewYear.”

Days later, Ferrera’s Sisterhood of the Traveling Pants costars — Blake Lively, Alexis Bledel, and Amber Tamblyn — reunited to celebrate her pregnancy. Ferrera posted a pic of the quartet on Instagram and used the opportunity to shine a focus on the Time’s Up movement. “Starting the New Year off with blessings from my Sisterhood,” she wrote. “We’ve got work to do for the next generation. Let’s get to it. #TIMESUP”

The next day, she sat down on The Late Show With Stephen Colbert to talk baby names. “I love my name now,” she told Colbert. “But growing up with the name America is not easy. I don’t want to put that on my child because I know what that feels like.”

We’d say Sebastian is the perfect choice.
