"They May Never Walk": Jesy Nelson Shares Devastating Health Update on 8 Month Old Twins

For Jesy Nelson, the journey into motherhood has been a series of high stakes hurdles. After a high risk pregnancy and the premature arrival of her twins in May 2025, the singer now faces her most daunting challenge yet. Taking to Instagram in early January 2026, a tearful Nelson informed her followers that her daughters have been diagnosed with Spinal Muscular Atrophy (SMA) Type 1, a severe and rare genetic condition that affects the motor neurons in the spinal cord.

The diagnosis came after months of uncertainty. Nelson admitted that the signs were initially subtle. It was her own mother who first noticed that Ocean and Story were not moving their legs as much as other infants their age. Because the twins were born at 31 weeks and five days, healthcare professionals initially advised Jesy not to compare them to full term babies.

"I'd been told, 'Don't compare your babies because they're premature. They won't reach the same milestones,'" Nelson recalled. However, as the months passed, more concerning symptoms emerged, including difficulty feeding and a lack of neck strength. After what she described as "grueling" appointments and assessments, the reality of their condition was finally confirmed.

Spinal Muscular Atrophy is a neuromuscular disorder that causes muscles to weaken and waste away. Type 1, also known as Werdnig Hoffman disease, is the most severe form and typically manifests within the first six months of life. It affects every muscle in the body, including those used for breathing, swallowing, and basic movement.

Historically, the prognosis for SMA Type 1 was bleak, with many infants not surviving past their second birthday. However, recent medical advancements have changed the landscape. Nelson confirmed that her daughters have already begun life saving treatments. "If they don't have it, they will die," she stated bluntly, highlighting the stakes of the condition.

The transition from pop star to full time medical carer has been profound. Nelson shared that she has "had to become a nurse" in the space of two weeks, learning to operate breathing machines and monitor her daughters' physical needs around the clock. "I literally feel like my whole life has done a 360," she said. "I almost feel like I'm grieving a life that I thought I was going to have with my children."

Despite the grief, Jesy and her fiancé, musician Zion Foster, remain steadfast. Zion shared a touching image of the twins on social media, noting that they were "still smiling through all the challenges." The couple is focusing on the "small wins" and the gratitude that their children are still here to fight.

A major part of Nelson's message was a plea for better diagnostic tools in the UK. She highlighted that countries like Australia and parts of the US and Europe include SMA in their newborn blood spot tests. In the UK, however, SMA is not yet part of the standard screening panel, meaning many cases are caught only after symptoms and irreversible nerve damage have already occurred.

Early detection is critical. When SMA is treated before symptoms appear, many children can follow near normal developmental pathways. Nelson urged parents to look for specific "red flags," such as: Floppiness or weak muscle tone. "Frog leg" positioning Rapid "tummy breathing" or a bell shaped chest. Difficulty swallowing or poor feeding.

While the medical consensus suggests that Ocean and Story may never walk or regain full neck strength, Jesy is not giving up hope. She cited the "transformative" nature of modern gene therapies and disease modifying treatments now available on the NHS."I truly believe that my girls will defy all the odds," she told her followers. "With the right help, they will fight this and go on to do things that have never been done."

The outpouring of support from the entertainment industry has been immense. Former bandmates and fellow celebrities have flooded her social media with messages of love, reflecting the collective heartbreak of a mother facing such a difficult path.
