Former Little Mix star Jesy Nelson was preparing to begin a new chapter of her life when she became a mother to twin daughters.

Instead, what followed was a months-long medical journey that would completely change her family’s future.

Her daughters, Ocean Jade and Story Monroe, were born prematurely at just 31 weeks on May 15, 2025. After spending an extended period in neonatal intensive care, the twins were eventually able to go home with their mother and father, Zion Foster.

But once they were home, Jesy’s family began noticing something that did not seem right.

The girls were not moving their legs as much as expected.

Then they began struggling to feed properly.

After months of appointments and uncertainty, the family received devastating news.

Both girls had been diagnosed with spinal muscular atrophy (SMA) type 1, a rare genetic condition that causes progressive muscle weakness.

For Jesy, the diagnosis changed almost everything she thought motherhood was going to look like.

The Twins Arrived Far Earlier Than Expected

Ocean and Story were born ten weeks early.

At only 31 weeks, the twins needed specialist neonatal care and spent a significant period in hospital before they were ready to go home.

Premature babies often reach developmental milestones at different times, and doctors had warned Jesy and Zion not to compare their daughters with babies born at full term.

Jesy was told to allow the girls to develop at their own pace.

Initially, the family believed that was exactly what was happening.

But gradually, concerns began to emerge.

The First Signs Were Easy to Miss

Jesy said her mother noticed that the girls were not moving their legs as much as they should.

Because the twins had been born prematurely, however, there was initially no obvious reason to assume that something more serious was happening.

Health visitors reportedly reassured the family that the babies looked healthy.

But the concerns did not disappear.

Their leg movement remained limited.

Then feeding became increasingly difficult.

For Jesy, those changes marked the beginning of months of medical appointments and uncertainty.

Eventually, doctors discovered the underlying condition.

The Diagnosis That Changed Their Lives

The twins were diagnosed with SMA type 1, the most severe form of spinal muscular atrophy.

SMA is a genetic disorder affecting motor neurons — the nerve cells responsible for controlling voluntary muscles.

As these nerve cells deteriorate, muscles become progressively weaker.

In severe cases, the condition can affect a baby’s ability to sit, move, swallow and breathe.

Jesy described the diagnosis as devastating.

In footage from her new documentary, she is shown struggling to process the news.

She said she could not believe what was happening and described the possibility of living with the consequences as heartbreaking.

For a mother who had only recently brought her premature daughters home, the discovery represented a completely unexpected new reality.

“I Feel Like I’m Grieving a Life”

One of Jesy’s most emotional reflections came when she described feeling as though she was grieving the life she had imagined for her daughters.

She had pictured watching Ocean and Story grow.

She had imagined ordinary childhood milestones.

Walking.

Running.

Growing up.

Instead, she was suddenly learning about breathing support, intensive treatment and the long-term effects of a serious neurological disease.

Doctors warned that the girls would likely face significant physical disabilities.

Jesy has said she was told they would probably never walk and might not regain full neck strength.

But she has also emphasized that the family is focused on treatment and giving the twins the best possible chance.

Why Early Diagnosis Matters So Much

SMA type 1 can progress rapidly, which is why early diagnosis and treatment are particularly important.

Jesy has made this issue central to her public campaign.

She has repeatedly spoken about the importance of newborn screening and argued that SMA should be detected as early as possible.

Her campaign gained significant public support.

More than 150,000 people signed her petition calling for mandatory newborn screening for SMA.

Following parliamentary debate, England announced plans to begin screening newborns for SMA from October 2026, although the initial rollout is expected to cover only around 72 percent of babies.

That limitation has become another focus of Jesy’s campaign.

She has argued that access to potentially life-changing treatment should not depend on where a baby happens to be born.

Jesy Wants Other Families to Have a Different Experience

For Jesy, the campaign is deeply personal.

She is not speaking about SMA as an abstract medical issue.

She is living with the consequences every day.

Her daughters’ diagnosis came only after months of appointments.

By sharing their story publicly, she hopes other parents and doctors will recognize potential symptoms sooner.

Her central message is that early detection can make a major difference.

She has repeatedly urged people to understand the importance of newborn screening and early treatment.

The goal, she says, is to prevent other families from going through the same uncertainty.

The Daily Reality Changed Completely

Since the diagnosis, Jesy’s life has become centered around her daughters’ medical needs.

She has described having to use breathing machines and carry out demanding care routines.

These are tasks that most parents never imagine having to perform for their babies.

The emotional burden is equally significant.

There is the fear of what the future may hold.

There are medical appointments.

There are difficult conversations with specialists.

And there is the challenge of watching two babies you love face a condition that you cannot simply make disappear.

Yet Jesy continues to describe the girls as happy and says they are doing as well as they can.

Her Relationship With Their Father Changed Too

The diagnosis also placed enormous pressure on Jesy’s relationship with Zion Foster.

The couple had been together for four years and announced their engagement only months before their relationship ended.

Jesy later explained that the traumatic experience had changed the dynamic between them.

She said that the twins remained their priority and that they were still friends and united in co-parenting.

Rather than focusing publicly on their separation, Jesy has emphasized the importance of working together for Ocean and Story.

Their daughters, she said, are their main focus.

The Documentary Shows a Side of Jesy Few People Have Seen

Jesy’s new Amazon Prime documentary, ** Jesy Nelson: Life Changing **, gives viewers a much more intimate look at what happened after the twins’ diagnosis.

The footage captures moments that are very different from the glamorous world associated with her career as a member of Little Mix.

There are medical appointments.

There are difficult conversations.

There are moments when she breaks down.

And there is the reality of caring for two babies with a severe medical condition.

For Jesy, making the documentary was clearly painful.

But she has said that it needed to be made if it could help create change.

From Little Mix Star to Mother and Campaigner

Jesy became famous after appearing on The X Factor UK and later becoming one of the four members of Little Mix.

The group went on to achieve major international success before Jesy left in 2020.

Her life after Little Mix has taken a very different direction.

Motherhood was already a major new chapter.

But the diagnosis of SMA transformed her public role again.

She is now using the platform she built through music to advocate for newborn screening and greater awareness of SMA.

Her campaign is no longer simply about her own children.

She wants the healthcare system to identify babies with the condition earlier so that other families have access to treatment as quickly as possible.

A Mother Refusing to Give Up Hope

Despite everything she has been told about SMA type 1, Jesy remains hopeful.

She has said she wants her daughters to defy the odds.

That hope exists alongside the reality of their condition.

She knows the road ahead will be difficult.

She also knows that medical treatment can make an important difference.

For Jesy, the answer is therefore not to pretend that the diagnosis does not exist.

It is to fight for every opportunity available to her daughters.

And to make sure other parents have the opportunity to act sooner.

The Bigger Question Behind Jesy’s Story

The story of Ocean and Story has raised a much broader question about newborn screening.

If a condition can be detected early and treatment can begin before irreversible damage occurs, how quickly should babies be tested?

Jesy believes the answer should be clear.

She wants SMA screening to become available to every newborn in England.

The current planned rollout is an important step, but she has continued to call for full coverage.

Her argument is simple: a child’s chance of receiving early treatment should not depend on their postcode.

The Two Little Girls at the Centre of It All

Behind the campaign, the medical debate and the documentary are two little girls.

Ocean and Story.

They arrived earlier than expected.

They spent weeks in neonatal care.

They eventually went home.

Then their parents discovered that something much more serious was happening.

Their diagnosis changed their family’s life.

But Jesy continues to describe them as happy and says they are doing as well as they can.

The family is now taking each stage as it comes.

Treatment.

Therapy.

Medical care.

And the everyday moments that still matter enormously.

A Story Jesy Hopes Can Change the Future

Jesy has said that she does not want other families to experience what hers has experienced.

That is why she continues to speak publicly.

That is why she has launched a petition.

And that is why she chose to document one of the most painful periods of her life.

Her daughters’ diagnosis has brought immense heartbreak.

But it has also given Jesy a purpose beyond simply telling her own story.

She wants newborn SMA screening to become more widely available.

She wants parents to recognize potential warning signs.

And she wants babies diagnosed with SMA to have access to treatment as early as possible.

For now, Ocean and Story remain at the centre of everything.

Their future is uncertain.

But their mother is determined to fight for every possibility.

And perhaps the most powerful part of Jesy Nelson’s story is that, despite everything she has been told, she is still looking forward — not backward.
