Born prematurely, the tiny but resilient Archer was quickly nicknamed their “little fighter.” In their social media post, Jesse and Katie wrote: “Our sweet Archie couldn’t wait to meet us and arrived a bit earlier than expected. We are so in love with him.” The images show him swaddled in personalized baby attire, his proud father serenading him to sleep, and his mother cradling him and reading softly—moments that reflect calm joy and deep emotion.

Big Sister Bailey Is Ready

Adding sweetness to the news, the couple introduced their dog Bailey—their beloved flower girl—as Archer’s canine “big sister.” Bailey could be spotted sleeping next to Archie’s blanket in one photo, signaling the family’s tight-knit bond and the loving environment waiting for him at home.

Moreover, the pregnancy announcement came on Valentine’s Day, February 14, with a charming joint Instagram photo and ultrasound image. Jesse joked it was for their “lil Valentine,” predicting an August arrival. A month later, they revealed Archer was a boy in a playful video featuring Bailey—it was Jessie’s parental moment, complete with tears.

In a March E! News interview, Jesse reflected on the transition to fatherhood, admitting caring for Bailey had been practice for raising a human. “We’ve done a pretty good job with our dog,” he said—but “it pales in comparison” to the responsibility of their baby boy.

A Family Built on Love and Laughter

Jesse and Katie’s relationship dates back to 2012, with a rustic Carmel wedding in October 2021 after nearly a decade of dating. He famously serenaded her on their first date and later in his wedding song “Party for Two.” Katie, an actress and broadcast journalist graduate, has described Jesse as thoughtful and prioritizing her amid his busy life—qualities that show more than ever in these first family photos.
