Mitt Romney acknowledged that he'd not heard the story of how his son reacted until that moment.
Mrs. Romney said that Craig, the youngest of her five boys, badly wanted a little brother or sister. When she became pregnant she said Craig was "thrilled."
"I knew I was losing the baby. It was about three or four in the morning and I decided that I wasn't going to wake Mitt up," said Mrs. Romney. "I waited until it was about six in the morning and I said, 'Mitt, you gotta take me to the hospital right now.'"
Mrs. Romney said Craig was "crestfallen" when he heard the news.
"I was home by the time he got home from school in the afternoon and he walked in the door and he was about ten or 11 years old and he fell on the floor and he just burst into tears," said Mrs. Romney. "And the poor little kid had been at school all day long holding this sorrow inside of him and having no one to speak to, no one to comfort him, no one to explain what is going on."
Romney said after his wife's story that he "hadn't heard the story of Craig coming home from school that day and being so devastated."
CNN previously reported Mrs. Romney's miscarriage. Sources confirmed to CNN that she was about four and a half months pregnant when it happened.
Mrs. Romney, age 63, has battled with multiple sclerosis since being diagnosed in 1998. Mrs. Romney also has described in an interview with CNN in August how she successfully fought an early-stage breast cancer diagnosis in 2008.
Mrs. Romney will speak Tuesday night at the Republican National Convention, creating a bookend effect with her husband as he and running mate Paul Ryan formally expect the Party's nomination on the final day of the convention Thursday.
