Little Arlo Lewis is almost seven years old but is still not able to talk, can barely walk and cannot be left on his own for even a minute.

But the boy from Brighton is a happy and healthy child, thanks in part to the help he receives from his foster carer.

Tracy Brown, 42, from Patcham, acts as a short break carer for Arlo, who suffers from global development delay and epilepsy.

The support Tracy gives to Arlo’s parents gives them some much-needed respite as well as offering the boy a treat.

She is now backing a campaign by Barnardo’s to recruit more foster carers.

Tracy said: “It would be extremely difficult for Arlo’s parents to cope if they couldn’t get the occasional break. His behaviour can be quite difficult at times and he cannot be left alone.

“It is so rewarding to be able to give them the space they need and it’s a joy to look after Arlo. He’s a lovely, happy boy and my three children adore him.”

There are currently 120 foster carers in Brighton and Hove but more are always needed, according to the manager of the city council’s fostering and adoption service, Clare Smith.

She said: “There is a high demand for foster homes to look after children who come into the care of the council. “We need foster carers of all backgrounds for children of all ages and the main requirement is the ability to provide a stable, loving and safe home for sometimes very demanding children. “Yes it’s challenging but as many of our foster carers tell us, it’s also hugely rewarding. “ For more information contact the fostering and adoption service on 01273 295444 or Barnardo’s on 01273 295179 or www.barnardos.org.uk.
