Mother's Day Miracle: 6-Year-Old's 911 Call Saves Mom

— -- After her 6-year-old's "calm and collected" demeanor during a medical emergency, Southern California mom Jovanna Nunez said today her daughter is her "hero."

When 6-year-old Madison found her mother unconscious Saturday morning in her Hemet, California, home, she called her grandparents for help.

"Madison contacted my parents telling them I was frozen," Nunez, 30, told ABC News today. "My eyes were wide open, I was unresponsive... My parents live in Japan and they were the ones who told her to call 911."

The Hemet Fire Department responded and found Nunez unresponsive but breathing, according to a statement from the fire department.

Nunez said when she woke up, there were EMTs surrounding her bed.

"The little girl maintained her composure" the whole time, the fire department statement said.

"[Madison] seemed calm and collected when I came to," Nunez said. "She was still on the phone with my parents... To my parents she did seem worried, but when I saw her she seemed very calm."

Nunez was hospitalized and released later Saturday. She said she apparently went into a diabetic coma, but was feeling much better today.

Nunez called Madison "my hero" and said she talked to her daughter Saturday about the importance of calling 911.

"The first thing she told me was that she's glad that [her grandfather] answered the phone and told her what to do," Nunez said.
