The newest Bachelor baby has arrived!

Melissa Rycroft and husband Tye Strickland welcomed their third child on the evening of Wednesday, May 18, PEOPLE confirms.

Son Cayson Jack Strickland weighed in at 8 lbs., 12 oz. and joins older siblings Ava Grace, 5, and Beckett Thomas, 2.

“Welcome to the world, little one,” the new mom of three tweeted, along with a black-and-white photo of her and her newborn baby boy.

Former Dancing with the Stars champ and Bachelor winner Rycroft announced the impending arrival of the couple’s third child on Instagram in November, in a photo featuring their kids holding handprint-emblazoned signs reading “Big Brother” and “And then there were five.”

“This is definitely the last one … probably…” Rycroft captioned the sweet family photo. Soon after, they announced they were expecting a boy.

Late last month, Rycroft shared a hilarious Instagram post, making it clear she was ready for little Cayson to come out already. The dancer and former Dallas Cowboys cheerleader, 33, added just a simple hashtag caption to the snap: “#truth”.

As a new mom of three, Rycroft will definitely have her hands full. Five months after Beckett was born, she told PEOPLE, “I used to have all of this free time even with my one child, I have one more and I don’t sit down anymore, so it’s crazy.”

Luckily, though, husband Tye — whom Rycroft married in 2009 — is a rock star when it comes to co-parenting.

“I got lucky in the daddy department. Very, very lucky,” she said. “He’s a big help and if it’s one of those nights that I’ve done my duty, he’ll wake up with [Beckett] at six in the morning and take morning duty and let me get an hour or two extra sleep.”

E! News was the first to report the birth.
