“They came to the conclusion that Caleb’s seizures were arising from the left frontal lobe of his brain. This enabled them to remove most of the bad area,” he said.

Post surgery, Caleb was “doing well for around six months, only having seizures every 10 days in comparisons to multiple nightly previously”.

But since then, they have risen to up to 10 a night.

“Although this is still less than when he was first diagnosed, it’s still too much for him to live anything close to a normal life,” said his father.

His parents and supporters have, so far, raised more than £14,000 towards the £120,000 costs for a second operation in the US.

“We are really overwhelmed with the support we’ve had,” said Stewart.
