At the time of the pregnancy announcement, the Baldwins told PEOPLE, "We have 'somos un buen equipo' engraved on our wedding bands. We say that to each other all the time at home — that we're a good team. One of the most beautiful things my children have experienced with a big family is how the heart can grow with every new sibling."
"Our capacity to love continues to expand and we can't wait to embrace our new little one this fall!" they added.
