He should be diagnosed with a life-limiting mitochondrial disorder after suffering from seizures.
Speaking to hosts Holly Willoughby and Phillip Schofield, Jane ed, which is common in young children.
Leanne first blames Steve for this, but then seizures become more “frequent and worrying.”
Steve and Leanne are at war with each other because they both have different ideas of what is wrong with their son and how to deal with it, she said.
But ultimately, it brings the couple closer together as they get the “devastating” diagnosis.
The first signs that something was wrong were in February, when Oliver was napping a lot.
“He’s going to the hospital and the doctors are very concerned about why he has these attacks, and they can’t stop him,” said Jane.
“So obviously this sounds the alarm bell, and that’s when the story turns to its worst and in the weeks to come, we end up getting the diagnosis of what’s wrong with him and it becomes devastating for everyone involved. “
Jane said it was “overwhelming” to stage this story, during which the cast and crew sought advice from the Lily Foundation, a charity to help raise awareness and support families affected by mitochondrial disorders.
Jane also revealed a surprising fact about the actors playing Oliver.
While it was already common knowledge that twin actors were used to play it, she also said that a third and older child was used for wide shots and stunts.
This is probably due to the fact that there is a strict limit on the number of hours per day that child actors are allowed to work.
One viewer tweeted, “Looking at the interview with Jane Danson, you can tell from her emotions how much she devoted herself to her new screenplay.
“This dedication and her talent make me believe that she will give this scenario her justice. Leanne was definitely the right character to choose.”
Another added, “As a mom who lost 2 children to mitochondrial disease, thank you for your story.”
