What global developmental delay is
Global developmental delay (GDD) is a clinical description used for a young child — usually under five — who is significantly behind expectations in two or more areas of development, such as communication, movement, thinking and learning, or social and daily-living skills. It describes where a child is now; it isn't a fixed prediction of where they'll end up.
Crucially, GDD is a strong reason to act early rather than wait and see. Research on early intervention shows that early identification and support can significantly improve a child's prognosis.[]
What it looks like
- Reaching milestones (sitting, walking, talking, playing) noticeably later than peers
- Delays across more than one area at once
- Needing much more help than same-age children with everyday tasks
- Difficulty with communication, attention, or social interaction
- A parent's sense that "things aren't quite on track" across the board
How early intervention helps
GDD is the condition the NDIS early childhood approach was built for — and the approach is deliberately low-barrier: under sixes don't need a diagnosis to get connected to support.[][] Because delays span multiple areas, the plan is usually multidisciplinary:
- Speech pathology — understanding and using communication
- Occupational therapy — fine-motor, play, and daily-living skills
- Psychology — social, emotional, and behavioural development
The strongest results come from early, consistent support that's woven into everyday routines, with parents coached as the child's main teacher between sessions.[]
NDIS funding
The early childhood approach supports children younger than nine with developmental delay or disability.[] If your child is eligible, therapy is typically funded under Capacity Building — Improved Daily Living. We can help you assemble the evidence for an access request and connect the right disciplines. For families without NDIS funding, sessions are private-pay at the NDIS rate.
What a Hey Sprout plan looks like
Our single intake identifies which areas need support and routes you to a coordinated plan across the relevant disciplines — one story, not three forms. Sessions run online via secure video with parents closely involved, because the everyday practice between sessions is where most progress happens.
Frequently asked questions
What does global developmental delay mean?
It's a clinical description for a young child (usually under five) who is significantly behind in two or more areas of development — such as communication, movement, thinking, or daily-living and social skills. It describes the picture now; it doesn't predict the future, and many children make strong gains with early support.
Will my child catch up?
Every child is different. Early, well-targeted intervention can significantly improve outcomes and, for some children, reduce the chance of a later intellectual disability. The earlier support starts, the better the trajectory — which is exactly why we don't wait.
Do we need a diagnosis to get help?
Under the NDIS early childhood approach, children younger than six don't need a formal diagnosis to access early supports — developmental delay or developmental concerns are enough to get connected. We can help you navigate that process.
Which therapy does my child need?
It depends on where the delays are. Speech pathology supports communication, OT supports fine-motor and daily-living skills, and psychology supports social, emotional, and behavioural development. Many children benefit from more than one — and our single intake coordinates them rather than making you repeat your story.
How does the NDIS help?
The early childhood approach supports children under nine with developmental delay or disability. If your child is eligible, therapy is typically funded under Capacity Building — Improved Daily Living. We can help you assemble what's needed for an access request.

ADHD in children and adolescents
Attention-Deficit/Hyperactivity Disorder (ADHD) is one of the most common neurodevelopmental conditions in Australian children, affecting roughly 1 in 20.
Depression in children and teenagers
Depression in young people is more than sadness — and it's treatable. Psychology, especially CBT and IPT, helps. If your child is at risk, get help now.
Anxiety in children and adolescents
Anxiety is one of the most common mental health concerns in Australian children — and one of the most treatable. Online, NDIS-funded psychology support.
Autism (Level 1 and Level 2) in children
Autism is a lifelong neurodevelopmental difference. Level 1 and Level 2 children typically benefit from speech, OT, and psychology support — and most are NDIS-eligible.
