In January, the Backstreet Boys band member and his wife got candid about preparing for their third baby after suffering multiple miscarriages throughout the years — and why this pregnancy was a complete (but pleasant) surprise.

"I was fully set on just having two children and I had prepared for that and made arrangements for that," Lauren told PEOPLE at the time. "We were going to have two children and it was a surprise. I didn't find out I was pregnant till I was about five-and-a-half months pregnant. I didn't have any symptoms; I didn't have anything indicating that I was pregnant."

"One day I just — I felt something move in my body and I said, 'Nick, there's something not right. I think I need to go to the doctor. Something's wrong with me.' I was not supposed to be able to have any more children, so I never assumed that I was pregnant," she added.

Carter said, "With everything that 2020 has given to the entire world, I look at it as a blessing. We love our two children and we pride ourselves on being great parents."

Earlier in April, Carter got nostalgic on Instagram, sharing throwback photos of his firstborn.

"Going through some baby pictures of Odin. He's growing so fast," the proud dad wrote. "I'm just happy to be able to give my babies a happy, healthy and peaceful home where they always have their parents in their lives to guide and love them unconditionally."
