Kimberly said she found the first two years of Harvey’s life difficult as she struggled to communicate with her son, and had to leave work to care for him as he was becoming increasingly distressed attending a mainstream nursery.

Disability charity Sense eventually assigned a specialist in working with deafblind children to the family, which Kimberly said was “life-saving” for her.

She added: “I was so anxious when I found out Harvey was deafblind, so his character’s storyline resonated with me a lot.

“I didn’t have any experience with disability and I kept imagining the worst-case scenarios.

“Luckily, with the support of organisations like Sense, Harvey is now a really happy child who is eager to learn, loves exploring and has a cheeky personality.”
