Help Oliver get his operation

I'm fundraising for my real life little superhero Oliver who's the most courageous determined little boy I've ever met.
 Born at 28 weeks due to numerous complications he has spastic deplegic cerebral palsy and epilepsy but he never let's that get him down even this year when he had his first big operation to rotate and reposition both hips which they had to break and reset both his legs he was still his cheeky self. 
We have been looking into ways to help long term manage pain especially as he gets older and would like to raise money for an operation called SDR not available on the NHS. 
SDR is an operation used to improve spasticity/tightness in children with cerebral palsy and Oliver is a good candidate to have this done it's going to be a big operation and recovery but long term will be worth it.
We would be so very grateful for any contributions donations to help Oliver.
