When to Be Concerned: Developmental Issues in Children 0-5 Years & What to Do
Sepetember 27, 2025
Early signs, milestones & how Nexia guides families when children aged 0-5 show developmental concerns.
Children (0-5 years) presenting with developmental concerns often leave parents with questions, worry, and uncertainty. During these early years, children grow rapidly across speech, movement, social skills, and emotional regulation. While differences in development are expected, persistent delays or unusual patterns can be signs of underlying concerns.
Early recognition is critical. The first five years are when the brain is most adaptable, meaning timely support can have life-changing outcomes. Whether a child struggles with speech, motor skills, or social interaction, early assessment and intervention can make a remarkable difference.
At Nexia Health Care, our role is to support families who suspect developmental issues, providing clarity, professional assessment, and practical strategies. This guide will help you understand developmental domains, recognise signs, and know when and how to seek help.
Children (0-5 years) presenting with developmental concerns may show delays in speech, motor, social or cognitive skills.
Red flags vary by age, and regression is particularly important to note.
Parents can support their child at home with play, communication, and daily routines.
Professional assessment provides clarity and guides next steps, with private services often faster than public.
Nexia Health Care offers comprehensive, family-centred support, helping families access intervention when it matters most.
Children develop at different rates, but most milestones fall within certain ranges. Development is usually measured across four main domains:
Gross motor: sitting, crawling, walking, running, jumping.
Fine motor: using fingers to grasp objects, stacking blocks, drawing, using utensils.
Delays may show up as clumsiness, late walking, or difficulty holding small objects.
Receptive language: understanding words and instructions.
Expressive language: babbling, speaking words, forming sentences.
Delays can include limited vocabulary, unclear speech, or difficulty following directions.
Interacting with peers and adults.
Sharing, turn-taking, showing empathy.
Regulating emotions and behaviour.
Concerns may include withdrawal, difficulty engaging, or intense tantrums.
Problem-solving, memory, attention span.
Pretend play and imaginative thinking.
Early numeracy or literacy skills.
Delays may show up as difficulty following routines, trouble learning colours/shapes, or struggling with focus.
It’s natural for children to reach milestones at different times. However, consistent delays across several areas, or regression (losing skills), can be concerning.
0–12 months:
Limited eye contact or smiles.
Not rolling over by 6 months or sitting by 9 months.
Not babbling by 12 months.
1–3 years:
Not pointing or gesturing by 18 months.
Very limited vocabulary or not joining two words by age 2.
Difficulty walking, frequent falls, or stiff/uncoordinated movements.
Lack of pretend play or not imitating others.
3–5 years:
Struggling to form sentences or speak clearly.
Difficulty playing with peers, sharing or turn-taking.
Intense tantrums beyond what is typical.
Trouble with fine motor tasks like drawing or using scissors.
Some children are late talkers but catch up quickly.
Temperament differences mean some may be shy, others very active.
Occasional clumsiness or selective eating is usually typical.
Still, if concerns persist, it’s best to consult a professional rather than wait.
Parents and carers are a child’s first teachers. While professional assessment is important, there are simple things families can do daily:
Talk often: describe what you’re doing, ask simple questions.
Play together: building blocks, pretend play, and outdoor games help multiple domains.
Read books: even toddlers benefit from storytelling and picture books.
Encourage independence: let them try feeding themselves, dressing, or tidying up.
Track milestones: keep a journal of what your child can do at different ages.
If you notice persistent challenges, use these notes to share with your GP or specialist.
When developmental concerns are present, a structured assessment can clarify what’s happening.
Professionals may use:
Developmental milestone checklists.
Observations of play, interaction, and communication.
Standardised tools like the ADOS-2 (for autism spectrum) or Bayley Scales (for infant development).
Public services: Usually require GP or child health nurse referral. Wait times can be long—sometimes over a year.
Private services: Allow direct bookings and shorter wait times. These can provide quicker answers and earlier access to therapy.
Private assessments involve fees, but reports may support NDIS applications.
Medicare and private health insurance may cover some costs.
Schools and childcare often accept professional reports to tailor support.
At Nexia Health Care, we understand that the journey from noticing concerns to seeking answers can feel overwhelming. Our services are designed to provide clarity, support, and practical solutions.
We bring together paediatricians, psychologists, speech pathologists, and occupational therapists. This ensures a holistic view of your child’s development.
Parents can contact us directly to arrange assessments without long delays.
Foundations for Growth: Focused on communication, behaviour, and learning skills.
School Readiness Program: Prepares children for transition into structured education.
Reports suitable for NDIS or school funding applications.
Tailored therapy plans for speech, motor, or behavioural support.
Guidance for parents to use strategies at home.
By acting early, families often find greater peace of mind and children gain access to services that set them up for success.
Brain plasticity: Skills learned in the first five years form lifelong foundations.
School readiness: Children with developmental delays may struggle academically and socially if not supported early.
Family wellbeing: Parents often feel empowered when they know what’s happening and have a clear plan.
Funding pathways: Many supports (NDIS, school adjustments) require professional reports.
Delays in speech, motor skills, social interaction, or emotional regulation are common signs that may require assessment.
If delays persist, or if skills are lost after being gained, it is best to consult a health professional as soon as possible.
Assessment usually involves observation, developmental checklists, and standardised tools by a multidisciplinary team.
Some children progress at their own pace, but persistent or multiple delays often benefit from early intervention.
Nexia offers private assessments, therapy programs, and family-centred strategies to support early growth and learning.
The early years are a window of opportunity. If you notice concerns in your child’s development, trust your instincts and seek guidance. You don’t need to wait for a referral or face long public waitlists, support is available.
At Nexia Health Care, our team is here to provide compassionate, evidence-based assessment and tailored intervention. With the right help at the right time, children can thrive, and families can feel confident in the journey ahead.
