Matilda Duncan and Casey Burke are two best friends with one thing in common. They both have cerebral palsy.
Though both girls move on frames an operation to make Matilda walk unaided is possible. But it costs £40,000. Casey's condition is too severe to have the procedure but she wants to help her best friend to be able to walk unaided. So she's started fundraising.
Casey is only 4-years-old. But she's leading the campaign to raise money for her friend. She said:
Her friend Matilda added:
So far, it has helped raise £17,000 on pounds in this site justgiving.com/walking-Matilda
But the money raised so far is still short of their target. Though donations were helped this week by diver Tom Daley supporting their cause.
Matilda hopes to have a revolutionary procedure - known as Selective Dorsal Rhizotomy - it involves cutting the nerves that cause cerebral palsy - and not everyone is able to have it.
The campaign is backed by children's charity Tree Of Hope and all funds will go to help Matilda.
