The new parents announced their big news over the weekend in separate Instagram postings.
Jessica uploaded several pictures of her new little bundle of joy and captioned them, "The last few days have been a blur and it's crazy this little man is ours! Welcome Westin Paul, we are so in love with you. We are all healthy and adjusting!"
"As exhausting as these first few days have been the snuggles really do make it all worth it," she added. "#babyboy #welcomebaby #parenthood #newbaby #family."
In one of the pictures Jessica posted, Westin was wearing a "Newest Member of The Hurd" onesie.
Austin uploaded similar images and added one of him appearing to hold his son for the first time in the hospital.
Austin wrote, "I'm a Dad! Happiest day of my life. As proud as I am to be a father to Westin Paul Hurd I am even more proud of my wife."
"All she needed to go through as a mother, the ups and downs of pregnancy, working her stressful job throughout and needing to do c-section when it wasn't in the plans," he continued.
"So much respect to all mothers and all they go through! Very thankful we are going home with both of them strong and healthy. Can't wait to see him grow and our family grow with him. #dad #family."
Westin was born weighing seven pounds and 12 ounces, and he measured 20 inches, according toUs Weekly.

A representative told the magazine after Westin's arrival, "The three [of them] are healthy and blissfully not getting any sleep."
Ironically, Jessica was pregnant at the same time as her twin sister, Jennifer Snyderman, and the women were only four weeks apart.
Jessica and Austin first shared their pregnancy news with the world in late July, one month before the couple's two-year wedding anniversary.
Jessica and Austin, who share a dog Rex, explained in July how they had been waiting "for the right time" to start a family.
"Now that we have been married for almost two years and are a little more settled with a house, we are as ready as we can be!" Jessica and Austin told E! News this past summer once they discovered they're expecting.
On the July 28 episode of Married at First Sight: Couples Cam's third season, viewers watched Jessica tell her husband on-camera that she's going to be a mom.
Jessica admitted she and Austin had just begun trying for a baby and so neither of them probably anticipated on getting pregnant so quickly.
When Jessica showed Austin her positive at-home pregnancy test, Austin, seemingly in disbelief, repeatedly asked, "What?! Are you serious?! What?"
"Finding out that Jess is pregnant is the best surprise," Austin said after hugging his wife.
"I just cannot believe it happened this quick. I am going to be a father. I have prepared myself for this. I've looked forward to this with Jess. I'm just so excited."
Jessica went on to gush about how "happy" she was to hear the excitement in Austin's voice.
"I have always wanted to become a mom," Jessica shared in the footage, "but the fertility issues that ran in my family always made me wonder if it was meant to be and it's crazy to think that less than two years ago, Austin and I met at the altar and now we're going to be parents."
Jessica celebrated the baby with her family and friends during an October 9 baby shower, and then she and her husband revealed in late October they had a baby boy on the way.
During a June episode of Married at First Sight: Couples Cam, Jessica and Austin were shown agreeing to start trying for a baby.
While Jessica clearly had baby fever at the time, Austin needed a little convincing since he wasn't sure they were 100 percent ready for a baby. Austin said he didn't want to rush into expanding their family like he had rushed into marriage.
But after talking things through, Austin determined he and Jessica were in a good place financially and emotionally and could raise their child in a stable home, especially since they had purchased a house in Fall 2020 and recently moved in.
Jessica was a 31-year-old nurse manager from Oak Harbor, OH, when she married a total stranger, Austin, who was a 31-year-old network technician from Maryland, on Married at First Sight in early 2020.
Jessica and Austin, who are both quirky and fun-loving, seemingly had the strongest and most stable relationship on Married at First Sight's tenth season.
In fact, the pair actually toned down their physical affection when in the presence of the other struggling couples.
Jessica and Austin consummated their marriage early into their honeymoon in Panama and succeeded in navigating the highs and lows of daily life together.
Austin, for example, cooked and cleaned the apartment when Jessica worked late, and for those reasons, Jessica didn't mind making more money than her husband.
Jessica and Austin had a little tiff about how much Austin had to travel for work and Jessica, but his schedule eventually changed and Jessica's job became more demanding when she was asked to run a COVID-19 unit.
However, the couple continued to support each other and grow more in love.
