Teigen then explained why they named their baby Jack, noting that he "worked so hard to be a part of our little family, and he will be, forever."
Last December, Teigen revealed she had given up drinking and celebrated "4 weeks sober"in a video shared on social media.
During an appearance on "The Ellen DeGeneres Show" back in February, Teigen shared how the loss of her baby was "transformative."
"In a way, he really saved me because I don't think I would have discovered therapy and sobriety and this path of really feeling good about myself," Teigen said of her late child.
Teigen recently shared that her third book, "Cravings: All Together: Recipes To Love," is dedicated to her late son. It will be released on October 12.
