Jesy Nelson’s Twin Daughters Diagnosed with Spinal Muscular Atrophy: A Mother’s Heartbreaking Battle and Unwavering Hope

In a deeply emotional revelation that has resonated across the globe, former Little Mix star Jesy Nelson has shared the heartbreaking news that her twin daughters, Ocean Jade and Story Monroe Nelson-Foster, have been diagnosed with a severe genetic condition: Spinal Muscular Atrophy (SMA) type one. The 34-year-old singer, alongside her musician fiancé Zion Foster, welcomed the twins in May 2025, following a high-risk pregnancy that was already a testament to their resilience.

Nelson, visibly distraught yet determined, conveyed the devastating prognosis in a self-filmed video shared on Instagram. Medical professionals have informed her that her beloved girls will likely never walk and may struggle to regain neck strength, facing a future marked by disability. This stark reality has plunged the new mother into a profound state of grief, as she openly admitted, “I am grieving a life I thought I was going to have with my children.”

The Unseen Battle: Unraveling Spinal Muscular Atrophy

Spinal Muscular Atrophy (SMA) is a rare and severe genetic disorder that progressively destroys motor neurons, the nerve cells in the brainstem and spinal cord that control voluntary muscle movement. As Nelson bravely explained to her followers, SMA type one affects every muscle in the body – from the legs and arms to the crucial muscles needed for swallowing. In its most severe form, if left untreated, the disease tragically means a baby’s life expectancy may not extend past the age of two.

The symptoms of SMA vary among individuals but can include a range of debilitating issues. According to Metro, these may involve bone and joint problems such as an unusually curved spine (scoliosis), significant muscle weakness leading to floppy or weak limbs, and severe movement problems making it difficult to sit up, crawl, or walk. Additionally, individuals with SMA often experience issues with breathing or swallowing and may exhibit twitching or shaking muscles (tremors). For Jesy’s twins, the diagnosis of type one means an aggressive progression, making early intervention not just crucial for quality of life, but for survival itself.

“Over time it kills the muscles in the body,” Nelson explained, highlighting the critical urgency associated with the condition. “If it’s not treated in time, your baby’s life expectancy will not make it past the age of two.” Thankfully, her daughters have received vital treatment, a process she described as “very rapid” once the diagnosis was confirmed. “Time is of the essence with this disease… If they didn’t have it they would die,” she emphasized, underscoring the life-saving impact of the medical care they’ve received.

A Mother’s Intuition: The Grueling Path to Diagnosis

The journey to this devastating diagnosis was not straightforward. Jesy recounted how her mother first noticed the twins weren’t moving their legs as much as expected. Initially, Nelson herself didn’t perceive it as a major concern. Having given birth prematurely at 31 weeks after a complicated pregnancy, she had been advised by medical staff not to compare her babies to others, as premature infants often reach milestones later. “From the minute I left NICU I was told, ‘Your babies are premature so don’t compare your babies to other babies. They won’t reach the same milestones just take them as they are,’” she recalled.

Healthcare visitors initially reinforced this perspective, assuring her that the girls were healthy. However, subtle signs began to emerge, particularly struggles with feeding. “There were a few signs later on that the girls were struggling to feed properly. We would take them to the GP and say ‘Our babies are not feeding as frequently as they should.’ They said it was fine and to try little and often,” Nelson shared. These seemingly minor issues eventually snowballed into a relentless pursuit for answers.

What followed were what Jesy described as “the most grueling three to four months and endless appointments.” It was a period of profound uncertainty and anxiety, culminating in the devastating news delivered at Great Ormond Street Hospital. The singer’s experience highlights the challenges many parents face in navigating complex medical issues, especially when initial symptoms are subtle or can be attributed to other factors.

A Pregnancy Marred by Complications, Documented for the World

This latest challenge comes after an already arduous pregnancy journey. Jesy’s pregnancy was far from typical, marked by significant complications that tested her physical and emotional limits. She underwent emergency surgery after her girls were diagnosed with twin-to-twin transfusion syndrome (TTTS), a serious condition affecting 10 to 15% of identical twins who share a placenta. TTTS occurs when abnormal blood vessel connections in the placenta lead to an imbalanced blood flow between the twins, causing one to receive too much and the other too little. Nelson spent ten weeks in the hospital before giving birth prematurely.

The twins were also identified as monochorionic diamniotic (MCDA), meaning they shared a single placenta but had separate amniotic sacs. This complex medical background had already set the stage for a challenging start to motherhood.

Remarkably, Jesy and Zion had chosen to document this intensely personal and high-risk journey for a six-part Amazon Prime documentary series. Before the twins’ birth, Zion Foster spoke to The Mirror, reflecting on how the turbulent pregnancy had forged an even deeper bond between them. “We’ve literally grown to understand each other on a deeper level… And I think we really understand how much we actually care about each other,” he stated, anticipating the profound changes motherhood would bring. The documentary, initially conceived to capture the highs and lows of a new chapter, will now undoubtedly offer an even more poignant and raw look into the realities of their family’s life.

Finding Strength Amidst the Storm: A Mother’s Unwavering Hope

In the wake of the diagnosis, Jesy Nelson’s life has been irrevocably altered. She describes the hospital as her “second home” and herself as having had to become a “nurse within two weeks” of receiving the news. “I’ve had to do stuff no mother should have to do to their child,” she confessed, painting a vivid picture of the immense emotional and practical demands placed upon her.

Despite the overwhelming pain, Nelson’s message was ultimately one of resilience and hope. Breaking down in tears, she acknowledged the gravity of the situation but held onto a powerful belief: “I know I have to be grateful. At the end of the day they are still here and that’s the main thing. They’ve had their treatment.” Her voice, though trembling, carried an unshakeable conviction as she added, “I truly believe that my girls will defy all the orders and with the right help they will fight this.” It’s a sentiment that speaks to the profound strength of a mother facing unimaginable adversity, clinging to hope for her children’s future.

Jesy Nelson’s candid sharing of her family’s struggle with SMA type one not only sheds light on a rare and devastating condition but also serves as a powerful testament to the often-unseen battles parents face. Her vulnerability in revealing her grief, coupled with her fierce determination to advocate for her daughters, transcends celebrity status, offering a relatable narrative of profound love and unwavering hope in the face of life-altering challenges. It’s a stark reminder that even in the most public of lives, personal struggles can be deeply private and profoundly impactful.
