Global Developmental Delay
When to Refer a Child with Possible Global Developmental Delay
Refer when a child shows significant delay in two or more developmental domains, when a previously gained skill is lost (regression), or when delay comes with red flags like seizures, abnormal tone, or hearing/vision concerns. When in doubt, refer — early referral never harms.
You are often the first to notice when a child is slow to sit, speak or respond — and that early eye matters more than anyone tells you.
In short
Refer a child for specialist assessment when they show significant delay in two or more developmental domains (gross motor, fine motor, speech and language, cognition, or social/self-help) for their age — and refer urgently, without waiting, if a milestone that was once present is lost (regression), if there are seizures, or if vision or hearing seems impaired. One missed milestone may be normal variation; delays across several areas, or any loss of skills, always warrant a specialist opinion.When to refer — the decision points
Use the RBSK 4 Ds frame — Defects at birth, Deficiencies, Diseases, Developmental delay — and refer when you see:- Not sitting by ~9–10 months, not walking by ~18 months, no words by ~18 months, no two-word phrases by ~24 months.
- Delay across two or more domains — this is what defines possible Global Developmental Delay (in under-5s).
- Any regression — losing words, eye contact, or motor skills already gained. Refer the same day.
- Red flags alongside delay — poor feeding, abnormal muscle tone (floppy or stiff), no response to sound, no eye contact, or fits/seizures.
- Strong parental concern, even if your screen looks borderline — parents notice patterns first.
When in doubt, refer. Early referral never harms; delayed referral costs the child time that matters most.
The Pinnacle way
A frontline screen flags concern — it never confirms a diagnosis. A clinical AbilityScore®, and any diagnosis of Global Developmental Delay, are formed only at a Pinnacle Blooms Network centre under a qualified clinician's care, who looks for treatable causes first and builds a plan with the family. Across 70+ centres, our early intervention teams partner with ASHA and PHC workers so a flagged child reaches the right hands quickly.Trusted sources

What to watch
Refer the same day if a child loses skills already gained (regression), has seizures or abnormal muscle tone, or does not respond to sound. Refer too whenever a parent is strongly concerned, even if your screen looks borderline.
Try this at home
Keep a simple milestone note for each child you visit — sit, stand, walk, first words, two-word phrases. Comparing your last visit to this one makes a slowing or a loss far easier to spot than memory alone.

Frequently asked
What counts as Global Developmental Delay versus a single missed milestone?
Global Developmental Delay (in children under 5) means significant delay across two or more domains — such as motor, speech, cognition or social skills. A single late milestone in an otherwise thriving child is often normal variation; delay across several areas warrants specialist assessment.
Should I refer immediately if a child is losing skills?
Yes. Loss of skills already gained — words, eye contact or motor abilities — is regression and is a same-day referral, regardless of age. Do not wait for a follow-up visit.
What if my screen is borderline but the parent is worried?
Refer. Parental concern is one of the most reliable early signals and frequently precedes what tools detect. Early referral carries no harm; a delayed one costs the child valuable intervention time.
Does referral mean the child definitely has a disability?
No. A frontline screen only flags concern. A clinician at a specialist centre looks for treatable causes first and forms any diagnosis through a structured assessment — referral is the path to clarity, not a label.
