The Rita Rocks star was heartbroken when she discovered her eight-year-old son, Xen, was born with the disorder, which can impair social interaction and communication.
She tells People magazine, "I was crying, 'Why is this happening to my baby?' Will he be able to hear me? Will he be able to say, 'I love you?' Will he be independent?"
Campbell-Martin admits she was "nervous and scared" ahead of the September (09) birth of her new baby boy, Ezekiel. But the mother-of-two couldn't be happier with the couple's growing family.
She adds, "We waited a long time. I didn't know if I could handle two. We wanted to give Xen as much attention as possible. How do you give love to two human beings like that?... (Now) I can handle anything."
