Heartbroken mourners gathered today for the funeral of a Scots schoolboy who died days after he was granted access to a drug that could have helped save his life.
The potentially life-saving drug, by manufacturer Vertex, is not being licensed in Europe and unavailable on the NHS.
But the 13-year-old from Johnstone, Renfrewshire was allowed to take the medicine on compassionate grounds.
One day after Ayden's family shared the news that he would be offered the drug, his condition declined.
Doctors placed the young Rangers fan on a ventilator before he sadly passed away.
His distraught mum, Tracey thanked the droves of loved ones who attended Ayden's funeral on Monday.
Tracey, 33, posted her thanks on the Ayden's Journey Facebook page and shared a sweet snap of Ayden alongside a photograph of a rainbow, which fittingly appeared over Ibrox stadium.
The doting mum wrote on Facebook: "Today Ayden made his final journey in this world.
"I could never have prepared for today and I'm lost for words.
"I wasn't ready for you to leave us but I know you have to.
"The thought of life without you tears me apart and I tried so hard today to keep it together and give you the send of you deserved.
"I have never been more proud of anything in my life.
"And to see how many people you have touched in your short life overwhelmed me as soon as we arrived.
"Hundreds of people came today to pay their respects to you and I will be forever grateful."
Tracey opened up about the difficult journey her family will face going forward without the tragic teen.
She added: "Thank you to everyone who has messaged us lately and sent strength and support, it's got us through a tough time.
"But now we face going home and pulling our family together and living life without Ayden here.
"That will take time and our kids need us now more than ever because they are missing a huge part of their life."
Grieving loved ones were comforted by seeing a rainbow over Iborx stadium on the day of Ayden's funeral.
"Thank you to everyone today who helped us give Ayden the send off he so rightly deserved it means the world I only wish he could have seen it," Tracey said.
"Although the rainbow over Ibrox tells me he did."
The doting mum ended her post with a direct message to her 'hero'.
"Your time here with us on this earth may be done my boy, but this is only the beginning of your amazing legacy," she added.
"I will see you again one day but for now I will love you forever my hero.
"Your Mum, your biggest fan."
Distraught loved ones paid tribute to Ayden and offered messaged of support to his heartbroken family in their droves.
One mourner posted: "It was a beautiful service today and a fantastic turn out for an amazing, strong, brave wee boy.
"I have one very heartbroken wee boy tonight who is missing his friend very much."
Another added: "Ayden has really touched my heart.
"Your words over the past few weeks have brought me to tears.
"RIP beautiful boy."
A third commented: "Fly high beautiful little warrior.
"I can't even imagine were you are getting the strength from but I guess that's where this beautiful wee guy got his courage from,
"Stay strong as you now have a guardian angel with you all day everyday."
Rangers legends, Ally McCoist and Steven Gerard led tributes paid to Ayden in the wake of his death.
A minute's applause was held during the Gers' clash with St Mirren the week after the teen passed away.
