TAMPA – Ann Romney, who will soak up much of the focus at the convention here today, this morning revealed an account previously undisclosed – including, in some details, to her husband – about a miscarriage she had when she was in her 40s.

She told CBS’s “This Morning” that she got pregnant unexpectedly – because doctors had told her after surgery 10 years earlier that she wouldn’t have children again. But then one night she knew she was losing the baby. She waited several hours before waking her husband to take her to the hospital.

She also said that the youngest Romney son, Craig, who had always wanted a younger brother, was crestfallen by the news.

“I was home by the time he got home from school that afternoon,” Ann Romney said. “And he walked in the door, and he was about 10, 11 years old. And he fell on the floor and just burst into tears. And the poor little kid had been at school all day long holding this sorrow inside of him.”

The account is the type of raw, emotional, personal story that could help the presumptive Republican nominee make more of a connection with voters. Ann Romney arrived here this morning with her husband, and did a walk-through of the convention hall where she will deliver her address tonight around 10.

Ann Romney said in the interview that she had several miscarriages. Mitt Romney, sitting beside his wife for the interview, said he had been unaware of the story about his youngest son’s reaction upon hearing news of the miscarriage.

“I hadn’t heard the story about Craig coming home from school that day and being so devastated,” he said. “I’m not surprised. He’s a very tender heart and a wonderful father today himself.”
