and live on Freeview channel 276
The youngster inspired the duchess over how she coped with leukaemia during the pandemic.
A photograph of Mila kissing her father through a window went viral when published and became part of the Hold Still lockdown photograph initiative by the duchess.
Dad Scott left the family home for seven weeks to protect Mila and reduce the risk of infection being brought into the house.
He could only meet up with Mila, her sister Jodi and their mum Lynda when he visited but stayed in the garden while they remained indoors.
The youngster was just four months into her chemotherapy journey for acute lymphoblastic leukaemia when Covid-19 restrictions came into effect in March 2020.
Mila wore a green sequinned dress for the special occasion of 'Royal Carols - Together At Christmas' in Westminster Abbey which was recorded earlier this month.
After chatting briefly with the duchess, including revealing top of her Santa wish-list was a Barbie Dreamhouse, she gave a short reading and lit a candle.
The service was attended by the Duke and Duchess of Cambridge, as well as young carers, faith leaders and those who may have been more vulnerable or isolated during the pandemic.
Having spent the last two Christmas Days in hospital the Sneddon family are now looking forward to all being together at home this year.
