The blood transfusion service is facing its annual double whammy as donations drop and demand increases. A lot of regular donors are busy in the run-up to Christmas, or may not be able to donate because they have a cold.
So there's an appeal for more donors to come forward, and not just for blood - they're after your life-saving platelets as well.
Maddie has a rare blood disorder that covered her in blood blisters. She had to be taken by helicopter to the specialist regional centre, and she responded to treatment.
She was helped back to health by Chris Prout, who continues to donate his platelets. Donors don't often know where their blood or platelets go, but he met the family by chance. The platelets are extracted from the blood, and they have to be carefully matched to the recipient.
There's a real need for more donors, and not just for rare conditions like Maddie's Ideopathic thrombo-cyto-penic purpura.
Demand rises in winter, but donations drop in the weeks before Christmas.
Staff say there's no need to worry about needles and it's a charitable donation that won't cost you a penny.
