You will always hold a special place in our hearts as our first baby, even though we never had the chance to meet. Our love for you is endless. Though you didn’t get to experience this world, you played a vital role in ensuring that I could continue to be a part of it,” Carolina, 25, captioned her post.She continued:“If it weren’t for my worries about you, we might never have called for help and gone to the hospital. Because of that decision, I was in the right place at the right time during my first heart failure. This is just one of the many reasons I am alive today, able to embrace a normal life once again.”Carolina Matovac is a philanthropist.
