Mum Carol Baker is launching a campaign to raise more than £24,300 for an operation to help her son Oliver walk, surgery which is not available on the NHS.

Two-year-old Oliver suffers spastic diplegia, a form of cerebral palsy that means the muscles in his legs are always tight and he is unable to get about without a walker.

Despite this he loves being outdoors and Mrs Baker, of Victoria Drive, Lyneham, hopes that a private operation would allow Oliver to run around with his six-year-old brother Josh in the future.

The operation, which is not available on the NHS, would take place at Frenchay Hospital, near Bristol, but it will cost over £24,300. Oliver will also need intensive physiotherapy after the operation to help him learn to walk again.

Mrs Baker, 39, a logistical co-ordinator at RAF Brize Norton, said: “His condition affects the lower part of his legs, he can’t stand unaided.

“Apart from that he’s just like any other two-year-old. He’s a very outdoor child. He watches Josh playing and says ‘I want to do that’.

“We need to raise this money so we can get him up and walking.”

Mrs Baker and Oliver’s godmother Samantha Jones, an RAF medic at Abbeywood, near Bristol, will undertake a parachute jump on September 11 at an airfield in Oxfordshire to kick-start the fundraising.

After this Oliver’s dad Stephen, 42, who works for Haines Construction in Calne, plans a London-to-Paris bike ride.

Mrs Baker, who hates the feeling of falling, will jump with an instructor. She said: “I got put in hospital in April with severe depression, but now this has given me this bit of hope.”
