“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.
Said Carter at the time, “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.”
