The Bachelor Nation family keeps growing! Peyton Wright and Chris Lambton revealed that they welcomed baby number two on Sunday, December 16, adding a little boy to their growing family.

The couple’s newborn son is named Hayes Jennings, and it sounds like he’s already very adored by his 2-year-old sister. “Lyla James is in love with her baby brother,” the proud second-time parents told Us Weekly. “It’s adorable.”

Wright and Lambton first revealed they were expecting their second child in July. The pregnancy came as something of a surprise to the couple, who conceived their first child through IVF and didn’t expect to conceive again without assistance. They found out they were expecting as they were awaiting their second round of IVF.

“This was a different road for us as it was a complete surprise,” Wright wrote in a blog post at the time. “Lyla James was an IVF baby and we went through so much to bring her into this world. I just assumed that was how we would create all of our babies…..boy was I wrong!”

She and her husband chose to keep the sex of the baby a surprise until his birth. “The unknown is exhilarating and I am embracing this different experience and can’t wait to meet this baby in December,” she wrote at the time.

Lambton was the runner-up on Ali Fedotowsky’s season of The Bachelorette, while Wright competed for Andy Baldwin’s affections on The Bachelor season 10 in 2007. She also later appeared on Bachelor Pad in 2010, a pre-cursor to Bachelor In Paradise.

Congrats to the growing family!
