A seven-year-old girl with type 1 diabetes has landed a lead role in a Christmas musical.

April Olsen is set to play Susan Walker in Ponteland Repertory Society's production of 'Miracle on 34th Street: The Musical.'

Despite her diagnosis in January, April was determined to take centre stage.

Initially, she feared that she would not be able to participate in the show, with balancing the demands of her health and the commitment of a lead role seeming 'overwhelming' at first.

However, with support from her family, friends, and the cast, she has learned that 'diabetes won’t stop her from shining.'

April's mother, Hayley Grant, said: "It’s been a huge learning curve for all of us.

"But April is incredibly brave, and the way the cast has supported her has been truly amazing.

"She’s determined to show that nothing can stop her from pursuing her dreams."

The show is a family affair for April and Ms Grant, who will be playing Susan's mother, Doris Walker, in the production.

Ms Grant said: "This show is so special to us.

"Playing mother and daughter on stage is a once-in-a-lifetime opportunity, and it feels even more special knowing everything we’ve been through together this year."

Directed by Sarah Blythe in her directorial debut with the society, the production is said to be an uplifting and festive treat for audiences.

Ms Blythe said: "April is a true star in the making.

"Her energy, enthusiasm, and resilience have uplifted everyone around her.

"This production celebrates not just the magic of Christmas, but the power of perseverance and community."

Set in New York City, Miracle on 34th Street: The Musical follows Susan Walker and her mother Doris, a Macy’s executive who has raised Susan to believe there is no such thing as Santa Claus.

However, everything changes when they meet Fred Gaily, an ex-marine turned lawyer, and the new Macy’s Santa, Kris Kringle.

Performances are scheduled for November 15 at 7pm, November 16 at 2pm and 7pm, and November 17 at 2pm.

Tickets are available through the Ponteland Repertory Society website at www.pontelandrep.co.uk.
