Ring, which is owned by Amazon, has set up the “#RingandSing” campaign in the boys’ honour, challenging users to record themselves singing a Christmas classic of their own.
For every video shared, the company has pledged to donate £10 to the hospice.
Strathcarron CEO Mags McCarthy said: “It has just brought so much joy.
“It has blown us up so much, the fact they came up to Strathcarron. We’ve seen the comments on social media, people asking how they can donate, I think it is fantastic that it is because of these five wee boys.
“It is a hard time of year for a lot of families, there’s never a good time to deal with this, so I think the opportunity to have these moments just helps to uplift us, the families the patients.”
