Fisher and Underwood welcomed their second son, Jacob Bryan, on Jan. 21, 2019. Underwood revealed before announcing her pregnancy with Jacob that 2017 was a tough year — she suffered three miscarriages while trying to expand her family. She said of the birth of her rainbow baby: "Our hearts are full, our eyes are tired, and our lives are forever changed. Life is good."
On Jacob's second birthday, Underwood shared a throwback baby photo of her son on Instagram with the caption: "Jacob, we longed for you. We prayed for you. We walked a long, hard road in order to one day hold you. Today you are two. You are silly and strong. You love to play and sing and follow your big brother around. You are loved. You are cherished. You are an incredible blessing from God. Happy birthday, sweet boy!"
On his fourth birthday, Underwood reflected on how fast the time had flown. "This was yesterday . . . and now you are 4. 😩," she wrote beneath a baby picture of him. "Happy birthday, sweet Jake . . . my sunshine!!! God truly blessed us when he gave us the miracle of you!!! We love you! ❤️❤️❤️ Thanks, @iveycakestore for the adorable and delicious cake! You guys are the best! 🥳🎉🎈."
