Jordan is taking her son Harvey to see eye specialists in America in the hope they can treat his rare sight defect.
The model is in the US to promote her first Playboy centre-spread.
But she is also hoping to find a specialist who can help Harvey, who was born blind.
Jordan told The Sun that Harvey's plight has brought her closer to his dad, footballer Dwight Yorke.
She said: "Dwight refuses to accept the news. He calls every day and says he can't believe there is nothing the doctors can do.
"We'll try everything that's medically possible. We won't give up for Harvey's sake. I may not have a relationship with Dwight but we're united on our son's welfare."
