A Chorley-born mum has been overwhelmed by the response to a video appealing for help to cheer up her seriously ill son.
Five-year-old Seth Lane was born with a rare condition caused by a mutated gene which means he has no immune system.
He has been in a sterile room, nicknamed a “bubble”, at the Great North Children’s Hospital in Newcastle since January as he waits to have a life-saving bone marrow transplant.
His parents, Leanne and Nik, filmed a video of Seth asking people to wear his favourite colour, yellow, on Friday and share their photographs online so he can see them.
And they have been amazed by the response so far, with the video being viewed more than two million times and messages sent from all over the world.
The video, which features Seth holding up yellow cards with messages, has even been featured on television programmes as far away as the USA and Canada.
Leanne, who grew up in Chorley and returns regularly to visit her family, said: “I think I’m in shock. I don’t think it’s sunk in exactly how big this has been.”
She posted the video on a blog she set up to keep family and friends updated on Seth’s health, at ourlittlehero.wordpress.com.
She said: “We did a video to get family and friends and people to post pictures of themselves in yellow.
“He is five now and he will do anything for something yellow. He is like a magpie for yellow – he absolutely loves it.
“I thought it would cheer him up.”
People have already been taking pictures of themselves wearing yellow.
Seth loves Fireman Sam and has been pleased to receive pictures of firefighters around the world wearing yellow, as well as a yellow fire engine in the USA.
Leanne, 32, who now lives in Northamptonshire, said: “This has given him something to do and it’s totally cheered him up. He gets so bored in that room.”
Seth was diagnosed with X-linked severe combined immunodeficiency when he was six months old and had a bone marrow transplant.
Family and friends wore yellow when the transplant was being carried out to show their support for Seth.
But only a couple of years later, he returned to hospital when complications arose.
Since January, he has been living at the hospital and has been unable to see his brother Hugo, aged five months, apart from brief visits.
His room is ultra-hygenic, the air is filtered and anyone who spends time with him has to wash and scrub first.
Seth will have eight days of chemotherapy before a bone marrow transplant from his dad Nik in around five weeks.
His family will face an anxious wait to see if it has worked. If successful, it could possibly be a cure.
They are not raising money, but suggest anyone who does want to make a donation could support charity Bubble Foundation.
And they believe it has already led to more people joining the bone marrow donation register.
Staff and members at All Seasons Leisure Centre in Chorley are among those planning to wear yellow to show their support for Seth and his grandfather, who works there.
People can post pictures on Facebook, Twitter or Instagram with #wearyellowforseth on Friday.
