Jessy was rescued from a drug factory at just four months after being born to a methamphetamine addict. She was found with badly deformed legs and shockingly, her eyes were glued together.
But with help from her supportive and loving adoptive family, Jessy is overcoming the condition caused by her biological mother's addiction, and is now flourishing despite having both her legs amputated at just 11 months.
Jessy learnt to walk using prosthetic legs but at the end of last year she moved on to carbon fibre blades. She has recently completed her first mini marathon, the Kids Rock Run in Tempe, Arizona raising money for other children like her.
The brave little girl was adopted as a baby by Dawn and Aaron Hatch, and is described by proud mum Dawn as "brilliant, resilient and smart".
Dawn said: "A double amputee exerts 250 per cent more energy when walking than we do. It took us nine years to get her healthy enough to wear these running legs.
"A little three or four-year-old can't take in the 2100 calories needed to walk on artificial legs. So Jessy had to have a feeding tube inserted into her stomach to help beef her up. We just took it out in June 2011. After that she could have her running legs as she'd built up enough muscle mass."
Jessy, who has never met her real mum, but has visited her biological brother twice, hopes to continue running, and wants to take part in more marathons and triathlons to raise money for her charity, Jessy for Jeans, which collects unwanted jeans and other clothing for disadvantaged children.
What an incredible little girl, sounds like she has an amazing spirit.
Good luck Jessy!
