He celebrated his sixth birthday earlier this month.The family's statement on social media on Sunday said: “Our little warrior passed away yesterday at 1345.
“He was at home in the arms of mummy and daddy, with his big brother Ollie, his baby sister Sienna and all his family around him. “He fought so hard to the end, he wasn’t in any pain and he was peaceful.
“I cannot even begin to explain how we are feeling right now, heartbroken doesn’t even come close.”
