Sully's Mum, Lucy, shares her family's story.

"When Sully was born, he seemed perfectly healthy. He wasn’t feeding well and struggled with a lot of sickness and acid reflux, but these early symptoms were all just put down to normal newborn problems. Even his heel prick blood test came back fine. But when Sully didn’t hit any of his baby milestones, I began to get worried it was something more."

Then when Sully was four months old, he started to have seizures. Everything escalated from there. The first time it happened, he had three seizures over five hours. It was terrifying. Our other son Reuben was only two years old then and he saw it all happening. It was frightening for him to see me so distraught and to watch his little brother taken away in an ambulance. Afterwards, he was worried to come and see us in the hospital because it had scared him so much.
