A group of children and young people from a Leicestershire hospice were invited to 10 Downing Street for the Prime Minister's Christmas Party.
Ten families from Rainbows, in Loughborough were whisked to Number 10 where they met David Cameron and his wife Samantha on Monday.(15)
Children's entertainers Dick and Dom, some of the cast of Paddington along with Paddington Bear himself, princesses and Santa Claus were also there to greet the youngsters.
Rainbows was one of several charities chosen to attend the annual party, thanks to Loughborough MP Nicky Morgan who organised the visit.
Due to limited places, the children were all selected by ballot.
Six-year-old Reece, of Leicestershire was one of the children who attended the event. Reece has several rare genetic conditions to contend with, which meant he spent the first year of his life in the high dependency ward at Leicester Royal Infirmary.
He is able to walk, but is unable to cover any real distance due to his lung condition.
This is further complicated by the fact Reece, who has a tracheostomy, is very reliant on a ventilator and suction machine to help him breathe.
He is unable to speak but is quite proficient at signing.
Reece's foster mum, Yvonne, 57, said:"Despite Reece's ill health and complications, he is such a massive character.
"If he could talk, he would be the jester of the pack; he has such a fantastic sense of humour.
Yvonne, who to date has fostered 156 children, including four with palliative needs, added: "Reece just loved the visit to Downing Street; the whole day was amazing and he didn't stop.
"I would never have been able to put this on our list of things we would like to do and thanks to Rainbows it was achievable."
Amisha Patel (15), of Leicester, who is unable to talk or walk and has delayed development, also went to the party.
She also has epilepsy, is unable to feed and is blind in one eye.
Mum Meena said: "It was just a beautiful day, we really loved it. And it is something we never thought we would do.
"Amisha loved meeting Santa and she was also very excited to meet the Prime Minister."
Jo Sims, head of family support at Rainbows, added: "This was a wonderful day for the families who attended the Christmas party and they all said it was a magical and a once in a lifetime opportunity.
"We are delighted to have been given the chance to attend such a prestigious occasion and it is a memory our families can treasure."
