"Baby Dawson is here and healthy!" Jared, 33, captioned an Instagram video of himself breaking the news to his followers.
"Ashley is recovering and doing well! It really couldn't have gone much smoother. He's so sweet and beautiful and has been sleeping all day. Unlike his Mom and Dad who are on no sleep right now but it's totally worth it!"
Jared also shared in the video, "Mama Ashley is healthy and everybody is doing well and the labor went well."
Jared said he and Ashley hadn't slept much and so they planned to eat and sleep after their son's delivery.
"I'm really excited for you guys to see Dawson!" Jared gushed, smiling ear to ear. "I just wanted to give you an update, that everyone is doing well and everyone is healthy. So thumbs up!"
Congratulatory messages poured in from Bachelor Nation on Jared's post.
Tenley Molzahn wrote, "Welcome to the BEST chapter of your life Jared & Ashley! Congratulations. I'm so emotional over this."
Raven Gates -- who welcomed a son with husband Adam Gottschalk last month -- commented, "Yay!!!!! Congrats!!! Can't wait to see baby Dawson."
JoJo Fletcher wrote, "Yay!! Congrats you two!!! Way to go @ashley_iaconetti !!"
Ashley and Jared were living apart before the baby's birth, with Ashley preparing to deliver in Virginia at her father's hospital and Jared working at the couple's coffee shop and lounge in Rhode Island, which opened in December.
After about seven months of trying to conceive and Jared undergoing sperm analysis, the couple revealed during an Amazon Live session in July 2021 that they were expecting their first child and the baby was due on February 10, 2022.
Jared wrote on Instagram at the time how he appreciated his pregnant wife so much and thought she looked beautiful even when she felt sick.
"Ashley has been a trouper and I love her so much. Last night, she threw up five times throughout the night. It's been a very sick month for her," Jared revealed.
"I feel terrible because there's not much I can do except the occasional runs to the store for chocolate cake or to 7/11 for Slurpees. I love her very much, she's a strong woman and I know Ashley is going to be an incredible mother."
The pair then announced in August 2021 that Ashley was pregnant with a baby boy and they already had a name picked out for him -- a name Ashley had been sold on for about 20 years.
Ashley and Jared got married on August 11, 2019 at United Congregational Church Newport, RI, followed by a reception at Rosecliff, an oceanfront Gilded Age mansion in the seaside city.
Ashley has said in the past she would be happy to have up to three children.
The couple met in 2015 on Season 2 of Bachelor in Paradise, and they engaged in an on-again, off-again confusing romance on the show that simmered into a friendship in which Ashley largely pined for Jared as he dated other women on Season 2 and Season 3 of BIP.
Jared admittedly realized his feelings for Ashley and wanted what he couldn't have when she sparked up a romance with Canadian firefighter Kevin Wendt on The Bachelor Winter Games.
Jared eventually won Ashley over and the couple confirmed they were dating in May 2018.
