She has something blue!

Something Borrowed star Ashley Williams is a new mom after welcoming her first child with husband Neal Dodson on Sunday, Oct. 5, she tells PEOPLE exclusively.

Son Gus Williams Dodson was born at home, weighing 8 lbs., 8 oz., and measuring 20½ inches long.

“He’s gorgeous and healthy. So far he’s soothable and calm. Knock on wood!” the proud new mama tells PEOPLE, adding her son was born to an Alexi Murdoch song.

As for her baby boy’s moniker Williams, 35, explains, “His name is Gus. For no other reason than: Who doesn’t love a guy named Gus?”

The How I Met Your Mother actress, who also moonlights as a certified doula, was surrounded by a team of midwives, a doula and a chiropractor during the birth. “We felt so safe and so lucky to have had such incredible support,” she says.

Shortly after Gus’s arrival, Williams’s costar, Jim Gaffigan, congratulated the couple on Twitter — and started the countdown to more kids.

“Big congrats to @imthesmash & @nealdodson on the arrival of Gus! Only four more kids to go. #homebirth,” Tweeted the actor, who will star opposite Williams in an upcoming comedy series.

Williams announced her pregnancy in July, joking to PEOPLE, “After years of waiting for the perfect moment to have a child, we decided to go with this moment instead. And we couldn’t be more thrilled.”
