A 3-year-old girl used the simple song lyrics "911 green" to call 911 and get help after her pregnant mother fainted.

Jessica Eaves taught her daughter, Madelyn, the song a week before she fainted due to a medical condition called vasovagal syncope (vayzo-vay-gal SIN'-kuh-pea).

When the 24-year-old and 3-months-pregnant Eaves fainted, Madelyn picked up her mother's BlackBerry phone.

She pressed 911 and the green button and was connected to a dispatcher.

In the recently released 911 call, Madelyn was able to answer questions about her house and cars outside that led emergency workers to the home.

And this isn't the first time Madelyn has used a phone to call for help for her mother.

Eaves first learned of her condition a year ago and taught her daughter the lyrics "green, green, green."

When Eaves lost consciousness back then, Madelyn picked up a cell phone and pressed the green button which called the last person Eaves had called and that person called for help.
