Seven-year-old Cole Jay Gibson was killed alongside his mother’s partner when her Renault Kangoo crashed on the A9 on Friday night.
Hazel Gibson, 29, sustained serious injuries in the collision including a fractured collar bone, back and pelvic bone.
Hazel is currently 17 weeks pregnant. Her unborn child was unharmed in the incident.
Speaking from Ninewells Hospital she talked about the miracle of not miscarrying her unborn baby and that the decision to donate organs was one made by Cole himself at a young age.
She said: ‘‘Cole decided he wanted to be on the organ donor register when he was 5 years old after he picked up a leaflet that came through the letterbox. We made a decision then as a family that it was what we all wanted to do and we are now all on the organ donor register.
