Inside a Toddler’s Medical Mystery: How One Family Copes When Doctors Don’t Have Answers
For more than a year, 14‑month‑old Elyza has lived with a mysterious illness that leaves her floppy, weak and unable to feed normally. Her mum, Yasmin Whittington, left her job to care for her full time while their family waits, and waits, for a clear diagnosis. Their story, shared by Yahoo News New Zealand, is heartbreaking—but sadly, not unique for families navigating rare or undiagnosed conditions.
When your baby misses milestones, can’t hold up their head, or struggles to eat, every day can feel like an emergency with no clear plan. Medical teams may be compassionate yet still say, “We don’t know yet.” This article unpacks what we currently understand about conditions that cause “floppiness” (severe muscle weakness) in toddlers, why answers can take so long, and how families can protect their child’s health—and their own wellbeing—while living in medical uncertainty.
A Toddler’s “Floppiness”: What’s Happening to Elyza?
According to reporting from Yahoo News New Zealand and People, 14‑month‑old Elyza has:
- Severe muscle weakness, often described clinically as “hypotonia” or being “floppy”
- Developmental delays, including difficulty holding herself up and meeting motor milestones
- Serious feeding challenges that make it hard for her to take enough nutrition by mouth
- An undiagnosed condition despite multiple medical assessments over more than a year
Her mum, Yasmin, left work to become her full‑time carer. That decision is emotionally heavy and financially difficult, yet common among parents of children with complex medical needs.
“Undiagnosed conditions are far more common than most people realise. For some children, the search for answers takes years, and in a minority of cases, we may never find a single label that explains everything.”
— Paediatric neurologist, quoted in a 2024 review on rare diseases
While the specifics of Elyza’s case are personal to her family and her medical team, her situation highlights a broader issue: how do we care for children with profound weakness and feeding difficulties when the exact diagnosis is still a mystery?
Understanding Hypotonia and Muscle Weakness in Babies
When clinicians describe a baby as “floppy,” they’re usually talking about hypotonia—reduced muscle tone that makes the body feel soft or weak when you pick the child up.
Hypotonia isn’t a diagnosis by itself; it’s a symptom. Many different conditions can cause it, including:
- Brain-related conditions (central causes), such as certain genetic syndromes, brain malformations, or injury around birth
- Spinal cord and nerve conditions, which can interrupt signals from the brain to the muscles
- Neuromuscular junction disorders, where the communication between nerves and muscles is impaired
- Primary muscle diseases (myopathies and muscular dystrophies)
- Metabolic, mitochondrial, or endocrine conditions affecting energy and muscle function
In cases like Elyza’s, where symptoms are severe and diagnosis takes time, doctors often focus on two parallel paths:
- Investigating the cause with imaging, blood tests, and increasingly, advanced genetic testing
- Supporting function and safety right now, including nutrition, breathing, and physical therapy
Why Can It Take So Long to Get a Diagnosis?
It can be incredibly frustrating to hear “we’re still not sure” for months or even years. Yet for complex paediatric cases, this is sometimes the reality. Reasons include:
- Rare conditions: More than 6,000 rare diseases have been described, many first recognised only in the last few decades.
- Overlapping symptoms: Many neurological and neuromuscular conditions look similar in infancy—weakness, low tone, feeding problems—making it hard to pin down which one is present early on.
- Genetic complexity: Whole‑exome or whole‑genome sequencing can identify new gene variants, but it’s not always clear whether a particular variant is truly disease‑causing.
- Need for time: Some conditions only show their typical pattern as a child grows, so doctors may need to watch how symptoms evolve.
A 2023 paper in Orphanet Journal of Rare Diseases reported that families often wait 5–7 years on average for a confirmed diagnosis of a rare disease, underscoring the “diagnostic odyssey” many parents describe.
None of this makes the waiting easier. But understanding the reasons can sometimes reduce the guilt many parents carry—this is rarely about something you “missed” or “should have done sooner.”
Daily Life With a Medically Complex Toddler
For children like Elyza, the diagnosis search happens alongside very real, day‑to‑day challenges. Common issues for families include:
- Feeding: Difficulty swallowing safely, frequent choking or coughing, or low stamina while feeding
- Positioning and mobility: Needing full support to sit, limited ability to roll or reach
- Respiratory health: Greater risk of chest infections if cough is weak or swallowing is unsafe
- Sleep and fatigue: Disrupted nights for both child and caregivers
- Appointments: Multiple hospital visits, assessments, and therapy sessions
Many parents, like Yasmin, describe stepping into the role of carer, nurse, therapist, and advocate all at once. It’s exhausting—and it’s okay to say that out loud.
Evidence‑Based Care While You’re Still Waiting for Answers
Even without a firm diagnosis, there is a lot that medical teams can do to support a child’s health, comfort, and development. Typical elements of care may include:
- Feeding and nutrition support
A paediatric dietitian and speech–language therapist (or feeding specialist) can help assess:
- Whether your child is safely swallowing liquids and solids
- Which textures, positions, and feeding methods are safest
- Whether tube feeding is needed to maintain adequate nutrition
- Physiotherapy and occupational therapy
Gentle exercises, supported sitting, and play‑based activities can help maintain joint flexibility, reduce stiffness, and support early motor skills—even if your child is very weak.
- Respiratory monitoring
Children with severe muscle weakness sometimes need help clearing secretions, or closer monitoring during respiratory infections. In some cases, specialist respiratory support is needed.
- Early intervention services
Many regions offer government‑funded early intervention programs that provide in‑home or clinic‑based therapies focused on developmental skills, regardless of whether a diagnosis is confirmed.
Common Obstacles Families Face—and Ways to Navigate Them
Parents in situations like Yasmin’s often describe the same challenges. Here are a few, with practical strategies that research and clinical experience suggest can help.
1. Feeling dismissed or not heard
Some parents report being told to “wait and see” even when they feel something is clearly wrong.
- Keep a symptom diary with photos or short videos of concerning episodes.
- Write down three key concerns before every medical appointment.
- It’s okay to say, “I’m still really worried. What are we ruling out? What’s the next step?”
2. Burnout and caregiver stress
Studies on parents of medically complex children consistently show higher rates of anxiety, depression, and physical exhaustion.
- Ask about respite care or in‑home nursing where available.
- Accept concrete offers of help—meals, school runs for siblings, or laundry.
- Consider counselling or peer support groups (online or in person).
3. Financial strain
Like Yasmin, many parents reduce work or leave jobs entirely.
- Ask hospital social workers about disability benefits, travel assistance, or grants.
- Keep records of medical costs; some may be tax‑deductible depending on your country.
- Charities and condition‑specific foundations sometimes offer small grants for equipment or respite.
Becoming an Advocate When Your Child Has an Undiagnosed Condition
You shouldn’t have to be your child’s case manager—but in reality, parents often become exactly that. Advocacy doesn’t mean being aggressive; it means clearly and calmly ensuring your child’s needs are visible.
Some practical advocacy steps include:
- Create a simple medical summary
One or two pages with key diagnoses (or “unknown”), test results, medications, and emergency information. Bring it to every appointment.
- Ask for a key worker or care coordinator
Many hospitals can assign a nurse, social worker, or community coordinator to help join the dots between specialties.
- Know your questions before you go
- “What are the most likely causes we’re investigating?”
- “What symptoms would mean we should come to hospital urgently?”
- “Is there a geneticist or neuromuscular specialist we should see?”
- Connect with undiagnosed‑condition networks
Organisations in many countries (for example, undiagnosed or rare disease networks) share resources and may help with specialist referrals or research opportunities.
What Does Current Research Say About Undiagnosed and Rare Conditions?
Advances in genetics and neuromuscular medicine have changed the outlook for many children, but progress is uneven.
- Genomic testing: Large studies suggest that whole‑exome or whole‑genome sequencing can provide a diagnosis in about 25–40% of previously undiagnosed children with complex neurological symptoms.
- New disease genes: Each year, researchers describe new genetic conditions; some are added to existing panels, while others remain extremely rare.
- Emerging treatments: For a few specific conditions, such as certain types of spinal muscular atrophy, targeted therapies have transformed survival and function. However, these are still the exception rather than the rule.
Experts emphasise that while cutting‑edge therapies are exciting, the backbone of care for most children remains early, consistent supportive treatment: nutrition, respiratory care, physical and occupational therapy, and family support.
Caring for Yourself While Caring for Your Child
Parents often say, “I don’t have time to look after myself.” But you are part of your child’s care plan. Burnout helps no one—not you, not your child, not your family.
Consider small, realistic steps:
- Micro‑breaks: Five minutes of fresh air while a partner, relative, or nurse watches your child.
- One trusted person: A friend or family member you can text on the hard days who won’t try to “fix” things, just listen.
- Professional support: Many hospitals can refer parents to psychologists or social workers experienced in chronic illness and grief.
- Connecting with others: Online groups for undiagnosed or medically complex children can reduce the isolation of feeling “the only one.”
“Grief for the child you imagined and love for the child you have can exist side by side. Both are valid.”

Key Takeaways for Families Facing a Medical Mystery
Stories like Elyza’s highlight how strong, and how stretched, families can be when medicine doesn’t yet have clear answers. While every child’s situation is unique, some common principles apply.
- Your concerns are valid. If something feels wrong, you deserve to be heard and taken seriously.
- Supportive care matters. Feeding, breathing, and developmental support can be life‑changing, even before a diagnosis is found.
- Diagnosis can take time. This is about medical complexity, not parental failure.
- You are not alone. Other families are walking similar paths, and support networks exist in most countries.
- Your wellbeing counts. Looking after yourself is part of looking after your child.
If you recognise your own family in parts of Elyza and Yasmin’s story, consider this a gentle nudge to reach out—whether to your child’s medical team, a trusted friend, or a parent support group. You don’t have to wait for a diagnosis to ask for help.
