Prime Video's Jesy Nelson: Life Changing begins as a celebrity lifestyle documentary but shifts dramatically when the former Little Mix star's twin daughters are diagnosed with spinal muscular atrophy (SMA), a life-threatening muscle wasting condition. The film captures Nelson's subsequent campaign to include SMA in standard newborn screening in the UK.
From Beach to Hospital Room
The documentary opens with a clip of Nelson and her fiancé Zion Foster on a Cornish beach, discussing their twins' future. Within seconds, the scene cuts to a hospital room where the twins are tested for SMA. Nelson's mother, Janice White, first noticed the girls weren't kicking their legs, prompting the diagnosis.
Back at home in Essex, Nelson and Foster await a consultant's video call delivering the life-changing news. “I feel like I’m going to be heartbroken for the rest of my life,” Nelson says to the camera afterwards.
The Campaign for Newborn Screening
The documentary reveals that if Ocean and Story had been diagnosed at birth, gene therapy could have prevented muscle wasting. However, SMA is not part of the newborn screening in the UK, delaying treatment. The twins now require equipment to move, eat, sit up, and possibly breathe. Without diagnosis, they would likely have died by age two.
Nelson becomes a patron of SMA UK and confronts then-UK health secretary Wes Streeting on breakfast TV, driving the campaign. The documentary shows her touring a lab in Scotland, which tests newborns for SMA, highlighting the simplicity of the test: a quick heel prick with results in 66 minutes.
Intimate Family Moments
Every scene is affecting, but the quiet moments at home with Nelson's mother feel most authentic. White struggles to find a saucepan—most were thrown away after meals burned when the twins called out. Specialist chairs are hidden behind laundry because Nelson cannot yet bear to look at them.
The bond between Nelson and her mother is the heart of the film, supported by gallows humour. In one scene, they laugh at friends' concerns about bad luck from keeping a Christmas tree up after Twelfth Night. “I don’t think a tree’s going to matter at this point,” Nelson deadpans.
Occasionally, bravery slips. “One day, are [the twins] going to be mad at me because I didn’t see the signs earlier?” Nelson asks the producer, apologizing for “the outburst.” Viewers will want to reach through the screen and hug her.
Impact and Outcome
The day before the programme aired, the UK government announced that every baby in England would be screened for SMA from October. However, Wales and Northern Ireland remain uncovered. The documentary ends with a clip from Nelson's phone: a giggling Story says “Mumma” for the first time.
According to the documentary, the consultant noted, “We’ve already somehow wasted a lot of time [in treating the twins], as unfortunately SMA is still not part of the newborn screening in the UK.” Nelson's campaign aims to change that for all children.
