The proud parents dressed up their baby boy in a knit football-adorned cap and matching t-shirt (although it was blue-and-white, not green like Dad's New York Jets' team colors!) for his introduction to the world.
"Eric Thomas Decker II, Born in Castle Rock, CO, 9 lbs 20 ¼ inches," the 27-year-old country singer captioned in the adorable photo. "We are so overwhelmed with love and feeling so blessed to have him join our family❤️."
The excited couple, who have been married since 2013 and already have a 1-year-old daughter, Vivianne, welcomed Eric, Jr. on Sept. 4.
"Thanks for all the well wishes!" the 28-year-old NFL star tweeted on Friday. "Mama and baby boy are doing great!! Vivi is the sweetest big sister!"
Even though Jessie and Eric dressed their son in head-to-toe football gear, they originally had different athletic plans for him! Watch the video below to find out what sport they hope little Eric will play one day.
