Signs & concerns
Clinical Red Flags for Genetic / Chromosomal Syndromes
Refer a young child for genetic/syndromic evaluation when developmental delay co-occurs with structural red flags — two or more dysmorphic features, congenital anomaly, disproportionate growth, hypotonia, or a suggestive family history. Global delay with dysmorphism warrants clinical genetics referral and first-tier chromosomal microarray.
Read the answer AnswerClinical red flags for Global Developmental Delay warranting referral
Refer for Global Developmental Delay when a child under 5 shows significant delay across two or more domains — motor, language, cognition, social — and most urgently with any regression, abnormal tone, dysmorphism or persistent parental concern. GDD is a provisional descriptor; referral and early intervention should not await a final cognitive label.
Read the answer AnswerClinical Red Flags for Gross Motor Delay Referral
Refer for gross motor delay when milestones are clearly delayed for corrected age — no head control by 4 months, not sitting by 9 months, not walking by 18 months — or when there is abnormal tone, asymmetry, persistent primitive reflexes, or loss of acquired skills.
Read the answer AnswerClinical Red Flags for Hypotonia Warranting Referral
Hypotonia in a young child warrants prompt referral when red flags accompany it: feeding or respiratory compromise, weak cry, persistent severe head lag, areflexia, fasciculations, developmental regression, dysmorphism, or acute/progressive weakness. Distinguish central from peripheral patterns to guide investigation (CK, SMN1, neuroimaging, EMG/NCS). Acute-onset hypotonia is an emergency. Isolated mild low tone in a thriving, on-track infant can be monitored, but any clustering of features should trigger paediatric neurology and developmental review with concurrent therapy referral.
Read the answer AnswerClinical red flags for Intellectual Disability referral
Refer for assessment when developmental delay is global — spanning cognition, language, motor and adaptive domains — rather than isolated, and persistent across settings. Act most urgently on loss of acquired skills, persistent language milestone failure, adaptive shortfall, dysmorphism or genetic risk, and parental concern. An intellectual disability label is not assigned in early years; refer on the delay pattern.
Read the answer AnswerClinical Red Flags for Motor Planning Difficulties Warranting Referral
Refer a young child for praxis assessment when difficulty planning and sequencing novel motor actions persists across settings, is disproportionate to strength or tone, and impairs daily function. Red flags include trouble learning new motor tasks, inconsistent day-to-day performance, poor carry-over despite practice, and functional avoidance of dressing, drawing or playground play. These signal impaired ideation/planning/execution rather than weakness, and warrant onward developmental and OT assessment.
Read the answer AnswerNon-Verbal / Minimally Verbal: Red Flags for Referral
Red flags warranting referral for a non-verbal or minimally verbal young child include no babble by 9–12 months, no words by 16 months, under 50 words or no two-word phrases by 24 months, and any loss of speech or social skills at any age. Absent response to name, limited joint attention, and communicating only by leading also warrant assessment. Always exclude hearing loss first, and refer regression the same week without watchful waiting.
Read the answer AnswerClinical Red Flags for ODD Warranting Referral
Refer for ODD when angry/irritable mood, argumentative-defiant behaviour and vindictiveness persist 6+ months across multiple settings with functional impairment — most days under age 5, at least weekly thereafter. Always screen for comorbidity, conduct disorder and safeguarding concerns.
Read the answer AnswerPersistent Toe-Walking — Clinical Referral Red Flags
Refer a persistent toe-walker for asymmetric gait, restricted passive dorsiflexion or fixed equinus, hyperreflexia or spasticity, calf hypertrophy or Gower's sign, motor regression, or co-occurring developmental and social-communication concerns. Idiopathic toe-walking is a diagnosis of exclusion.
Read the answer AnswerPrematurity-Related Developmental Risk: Red Flags for Referral
Refer a preterm-born child when corrected-age milestones lag persistently, when tone or movement is asymmetric or abnormal, or when feeding, vision, hearing or behaviour raise concern — most urgently on asymmetric tone, persistent fisting beyond 3 months corrected, early hand preference, or loss of acquired skills. Score milestones against corrected age until 24 months.
Read the answer AnswerRett Syndrome Red Flags Warranting Referral
Refer urgently when a young child shows the Rett pattern: a period of normal early development followed by loss of purposeful hand use, emergence of stereotypic hand movements (wringing, washing, mouthing), deceleration of head growth, and language/social regression — typically 6–18 months. Route to paediatric neurology and clinical genetics for MECP2 testing.
Read the answer AnswerClinical Red Flags for School Readiness Gap
Refer a 4–6-year-old when delays persist across language, pre-academic, motor, attention or self-regulation domains, are out of step with peers, and aren't explained by hearing or sensory deficit. A cross-domain, cross-setting pattern — not a single weak skill — is the referral threshold, especially when parents or preschool staff are concerned.
Read the answer AnswerSelective Mutism red flags warranting referral in young children
Refer when a child consistently fails to speak in specific settings (typically school) despite fluent speech at home, the pattern persists beyond one month of starting school, and it interferes with education or social functioning — and isn't better explained by a language disorder, autism or an unfamiliar language.
Read the answer AnswerSelf-Regulation Difficulties: Red Flags for Referral
Refer a young child for self-regulation difficulties when emotional and physiological dysregulation is pervasive across settings, disproportionate to age, and impairing sleep, feeding, learning or relationships. Act promptly on regression, persistent inconsolability, or co-occurring developmental or medical red flags, and exclude medical mimics such as pain, reflux and seizures.
Read the answer AnswerSensory-Based Feeding Selectivity: red flags for referral
Refer for Sensory-Based Feeding Selectivity when it is severe, persistent and impairing — faltering growth, nutritional deficiency, a narrowing accepted-food range, mealtime distress disrupting family life, or signs of aspiration. Distinguish it from transient toddler neophobia.
Read the answer AnswerSeparation Anxiety Disorder red flags warranting referral
Refer when separation-related fear is developmentally excessive, persists four weeks or more, and impairs functioning across settings. Escalate urgently with school refusal, somatic symptoms without medical cause, low mood, or onset after trauma or loss.
Read the answer AnswerSocial Communication Difficulties: Clinical Red Flags for Referral
Refer when social use of language — reciprocity, adjusting to listener, reading inference and context — is impaired across settings, exceeds developmental expectation, and isn't explained by hearing loss, global delay, or autism with restricted/repetitive behaviour. Persistent parent or teacher concern is itself a sufficient trigger.
Read the answer AnswerClinical red flags for Specific Learning Disability referral
Specific Learning Disability is not formally diagnosed before about age 6–8. In younger children, refer when pre-literacy, language and numeracy precursors lag persistently despite adequate instruction, with intact hearing and vision — especially with a family history of learning difficulty.
Read the answer AnswerRed flags for Stereotyped Movement Disorder warranting referral
Refer for Stereotyped Movement Disorder when rhythmic, purposeless movements persist beyond age 3, impair function, cause self-injury, or arise with developmental concern — most urgently with self-injury, regression, abrupt onset, or features suggesting seizure rather than stereotypy.
Read the answer AnswerTourette Syndrome red flags for referral in young children
Refer when multiple motor and at least one vocal tic show a waxing-and-waning course beyond 12 months — most urgently when tics impair function, cause injury, or coexist with ADHD, OCD or anxiety. Atypical or abrupt onset warrants prompt neurology review.
Read the answer AnswerVisual Impairment Red Flags in Young Children
Refer a young child for visual impairment when there is absent fix-and-follow by 3 months, leucocoria (white reflex), persistent or acquired nystagmus, a manifest squint after 4 months, abnormal red reflex, or any regression in visual behaviour. Leucocoria and acquired nystagmus warrant same-day ophthalmology referral.
Read the answer AnswerWhat cognitive difficulties might a teacher notice in a young child?
A teacher may notice a young child who struggles to follow multi-step instructions, takes longer to grasp and retain new ideas, has trouble paying attention or finishing tasks, and finds problem-solving or pretend play harder than peers. A persistent pattern across weeks and settings — not a one-off — is what warrants a supportive developmental check.
Read the answer AnswerWhat cognitive milestones should a 12-to-18-month-old reach?
Between 12 and 18 months, most toddlers explore objects with purpose, find hidden toys, follow simple one-step requests, recognise named people and objects, imitate actions, and begin simple pretend play. Children vary widely, so steady progress and no loss of skills matter more than exact timing.
Read the answer AnswerWhat cognitive milestones should a 18-to-24-month-old reach?
By 18–24 months most toddlers begin pretend play, copy adults, find hidden objects, sort and match simple things, follow one-step instructions and explore cause and effect. These are guideposts, not a strict checklist — children vary. If several skills are clearly behind, or any are lost, a gentle developmental check brings clarity.
