A musical celebration has been held in memory of a 21-month old boy who died in his sleep.

Rex Gooden was put to bed for a nap at his family home in Westerham in February, but did not wake up. His cause of death remains unknown.

His parents, Camilla and Paul Gooden, began fundraising in the months after and so far £85,000 has been raised.

More than £11,000 of that total is profit from a musical celebration held at St Martin's Church in Brasted on Saturday and an ongoing auction in which participants can win One Direction tickets.

Mr and Mrs Gooden, from Brasted, will be giving this money to the Sudden Unexplained Death in Children charity, which works to increase awareness of cases like Rex's.

The concert, which was completely sold out, featured a host of local young artists and international star and winner of Holland's Got Talent, Amira Willighagen.

Young musicians Alma Deutscher, Columba Dromgoole-Cavazzi and Izzy Wicks also took to the stage during the event, which ran from 4.30pm to 6.30pm.

Mrs Gooden said: "The concert was perfect. It was magical and beyond my wildest dreams.

"The young people who performed were fantastic and absolutely beautiful. We had a full house and the level of talent was so high most of the audience were star struck.

"It could not have gone better. It was really nice to get a chance to thank everyone in the local area for supporting us through this time."

Unexplained deaths of sleeping toddlers, aged between one and two years old, happen around once a month in England and Wales.

The remaining £80,000 raised by the Gooden family will be put towards a two-year extensive research project, with the final aim of finding out why these unexplained deaths happen.

The Gooden couple are working with The Lullaby Trust, a charity dedicated to saving babies' lives and supporting families shattered by the death of a child.

On the JustGiving page which is collecting donations for the research, Mrs Gooden wrote: "Rex was a happy, healthy, extroverted little boy with a twinkle in his eye, a ray of sunshine with a gift for making people smile."

"One of the hardest aspects of losing Rex is that there is no explanation. As a result we are passionate about funding research into why toddlers unexpectedly and inexplicably die in their sleep."

A charity walk was in also held in April. More than 90 walkers turned up to Knole Park in a bid to raise money for the refurbishment of Brasted Chart children's playground in Rex's memory.
