When the Shah family found out their 10-month-old son was suffering from a rare blood dis-ease their whole world was torn apart.
Now in a bid to help save their son Jayden, Sunil and Alka Shah, are calling on Observer readers to find out if they could be bone marrow donors.
The couple, who also have an older son, Aman, three, are originally from India and know there is a greater chance of a match if the donor is from the same racial or ethnic background as Jayden.
Sunil, who lives with his family in Hallem Gardens, Hatch End, described the moment he found out his son was sick. He said: "For about a month Jaydon had been poorly. We took him to our GP and he was given antibiotics. Things didn't improve so we ended up taking him to A and E.
"We knew something was wrong because he was having more tests. Then we were told he had a rare blood disease and would need a bone marrow transplant."
Jayden was diagnosed with familial hemaphogocytic lymphiohistiocytosis which affects one in two million children.
He is being treated with chemotherapy and steroids at Great Ormond Street Hospital in central London.
His parents have no way of knowing how long he can recieve this treatment but are praying someone can save their little boy.
Sunil, who has taken time out from working as a solicitor to care for Jayden, said: "My wife and I are at the hospital every day. We have a lot of family and friends who are also supporting us. Hopefully he will be able to come home soon but until he has a transplant we never know if he will be okay."
Desperate to find a suitable match Mr and Mrs Shah organised a bone marrow registration drive on Monday (May 12) at Harrow Arts Centre in Uxbridge Road, Harrow, where around 200 potential lifesavers had their blood taken and sent off for testing.
Sunil said: "We had an amazing response. A lot of people were unknown to me and just came to support the cause. Anyone who joins the register could save not just Jayden's but another person's life.
"I believe a lack of awareness is the reason so few Asian people are on the bone marrow register. The register is also particularly short of male and other ethnic donors."
The Shah family will be holding another blood testing drive with the help of charitable organistation, Anthony Nolan Trust, at Tiger Tiger in Haymarket, Piccadily Circus, London.
