A mother has launched a New Year campaign to stop other children dying suddenly like her son.
Karen Reece spent Christmas mourning Daniel, 14, who died of a mystery condition, killing him in the night.
She watched a DVD of him laughing and joking. The footage was filmed by cameramen for TV's Wife Swap programme which the family was taking part in.
It was delivered to their home in Alton Street at Crewe just before Christmas and is now a poignant link with Daniel, who died on the day of filming.
Heartbroken Karen and her husband Darren hope it will shed light on why he was taken from them when he appeared so fit and healthy earlier in the day. Doctors put his death in September down to Sudden Arrhythmic Death Syndrome (SADS).
Little is known about the condition which occurs when the electrical flow to the heart is interrupted causing it to stop.
Daniel, a pupil at Ruskin Sports College in Crewe, was found dead in bed by his brother, Stewart, 18.
Karen's mission now is to stop it happening to other children by raising awareness of SADS and cash for the charity, Cardiac Risk in the Young (CRY).
She said: "When Daniel was asked what had changed since we did the Wife Swap, he said: 'Me and mum get on a lot better, because I know my mum loves me.'
"I can't get those words out of my head and every time I close my eyes I see his lovely face smiling at me from the TV."
Karen staged a charity auction at the Three Lamps pub in Crewe which raised nearly £1,500 for CRY. Stars from the Lyceum Theatre panto, Cinderella, heard about the event and came along to show support.
She is planning more fundraisers for 2007 and is in touch with other parents who have lost children to SADS.
Early symptoms can be dizziness or breathlessness. But often, as in Darren's case, it is a silent killer.
Karen, 35, added: 'People have seen me talking about Daniel in the Chronicle and wonder why id do it.
One cam up to me and said 'You have put the fear of God into me over my kid.'
The fact is we should all be aware. I don't want Daniel's death to be in vain.
