Early Signs of Down Syndrome at 12–18 Months
Down syndrome is usually known from birth and confirmed by karyotype, not first found at 12–18 months. At this stage watch development, not new signs: slower motor and speech milestones and low muscle tone are common and respond well to early therapy. Diagnosis and any AbilityScore® are formed only at a Pinnacle centre under clinician care.

By 18–24 months, Down syndrome is almost always already confirmed at birth, so this stage is about supporting development — watching gentler-paced movement, speech and learning, often with low muscle tone — and beginning early therapy, not searching for a diagnosis.
Read the answer AnswerEarly Signs of Down Syndrome in a 2-Year-Old
Down syndrome is almost always identified at or soon after birth via physical features and a karyotype test, not first found at two. By two, parents may notice slower-paced motor and speech milestones — signals to seek a supportive developmental check, never a cause for alarm.
Read the answer AnswerEarly Signs of Down Syndrome at 3 to 6 Months
Down syndrome (ICD-11 LD40.0) is usually identified at or near birth and confirmed by a chromosome test, so by 3–6 months most families already know. Gentle pointers at this age include low muscle tone, slower feeding and growth, and physical features present from birth — none diagnostic alone. The priority now is early heart, hearing and vision checks plus strength-based early intervention.
Read the answer AnswerEarly Signs of Down Syndrome in a 3-Year-Old
Down syndrome (ICD-11 LD40.0) is usually identified at birth via physical features and a karyotype test, not first noticed at age three. By the preschool years you observe developmental patterns: slower speech with stronger understanding, low muscle tone, later walking, and gentler learning progress — all signposts for support. Age three is an ideal time for a structured developmental check to plan speech and learning input.
Read the answer AnswerEarly signs of Down syndrome in a 4-year-old
Down syndrome is almost always identified at birth or in infancy and confirmed by a chromosome test — not first found at age four. In a four-year-old already diagnosed, the focus is supporting slower-developing speech, learning, motor and play skills, plus routine hearing, vision, thyroid and heart checks. If never assessed, a paediatric developmental review is the right step.
Read the answer AnswerEarly signs of Down syndrome in a 5-year-old
Down syndrome is identified at or soon after birth and confirmed by a karyotype test — not first spotted at five. By age five, focus shifts to the developmental profile: supporting clearer speech, learning readiness, motor skills, and ongoing hearing, vision and thyroid checks with your paediatrician. If your child is not diagnosed but you have broad developmental concerns, seek a general developmental and paediatric check.
Read the answer AnswerEarly Signs of Down Syndrome at 6–9 Months
Down syndrome is usually identified at or soon after birth via physical features and a confirming karyotype, not discovered at 6–9 months. At this age, watch how your baby grows — low muscle tone often means slightly later motor milestones. Early support helps; a calm developmental check is the right next step.
Read the answer AnswerEarly Signs of Down Syndrome in a 6-Year-Old
Down syndrome is genetic and identified at or near birth — not first spotted at age six. By school age the focus moves from signs to support: strengthening speech, learning, motor skills and attention, with routine health monitoring. If a child has no diagnosis but development worries you, a general developmental check clarifies what help fits.
Read the answer AnswerEarly Signs of Down Syndrome at 9 to 12 Months
Down syndrome is almost always diagnosed at or before birth, not spotted at 9–12 months. At this age, watch your baby's muscle tone, motor milestones and communication, and begin gentle early support — only a clinician can confirm any diagnosis.
Read the answer AnswerEarly Signs of Down Syndrome in a Newborn
Down syndrome is usually recognised soon after birth from a pattern of features — upward-slanting eyes, flat facial profile, low muscle tone, single palm crease, short neck — and confirmed by a blood test. No single sign confirms it; your paediatrician brings the picture together and early support helps your baby thrive.
Read the answer AnswerWhat are the early signs of Global Developmental Delay?
Global Developmental Delay shows as a child under 5 being significantly behind in two or more areas at once — late sitting or walking, few words, little babble or eye contact, and difficulty with play, feeding or self-care. A cluster of delays, or any loss of skills, is worth an early developmental check; only a clinician can confirm the cause.
Read the answer AnswerEarly signs of Global Developmental Delay at 12–18 months
Global Developmental Delay in a 12-to-18-month-old shows as a pattern of delays across two or more areas together — movement, communication, thinking, and social skills — rather than one missed milestone. Watch for not sitting or attempting to walk, no babble or first words, little pointing or response to name, and limited play. Any loss of skills warrants a prompt check. Early screening opens the door to timely support.
Read the answer AnswerWhat are the early signs of Global Developmental Delay in a 18-to-24-month-old?
Global Developmental Delay at 18–24 months shows as a pattern of delay across two or more areas at once — late or unsteady walking, very few words, limited following of instructions, little pretend play, and trouble with spoon-feeding or stacking. A single late skill is often normal; a pattern, or any loss of skills, is worth a screen.
Read the answer AnswerEarly Signs of Global Developmental Delay in a 2-Year-Old
Global Developmental Delay in a 2-year-old shows as significant lag across two or more areas at once — late or unsteady walking, few or no words, limited pointing and pretend play, and difficulty following simple instructions. A single late skill is often normal variation; the pattern across domains, or any loss of skills, warrants a developmental check. Only a clinician can confirm.
Read the answer AnswerEarly signs of Global Developmental Delay in a 3-to-6-month-old
At 3–6 months it is too early to diagnose Global Developmental Delay, as babies develop at different rates. Watch over time for poor head control, stiffness or floppiness, not reaching by ~5–6 months, no social smile by ~3 months, little response to sound or faces, or minimal cooing — and bring any persistent concern, or any loss of a skill, to a routine developmental check for reassurance or an early start.
Read the answer AnswerEarly Signs of Global Developmental Delay in a 3-Year-Old
At three, Global Developmental Delay shows as several areas lagging together — few clear words, not joining two or three words, unsteady movement, little pretend play, and needing much more help than peers with everyday tasks. One area alone is usually normal variation; a pattern across areas is the reason for a developmental check, never a home diagnosis.
Read the answer AnswerEarly Signs of Global Developmental Delay in a 4-Year-Old
Global Developmental Delay in a 4-year-old shows as a pattern of being significantly behind in two or more areas — talking, thinking, movement, self-care or social skills — together. It is a description, not a final diagnosis; a hearing check and an early developmental review help, and many children progress well with timely support.
Read the answer AnswerWhat are the early signs of Global Developmental Delay in a 5-year-old?
In a 5-year-old, Global Developmental Delay shows as being meaningfully behind age expectations across two or more areas at once — thinking and learning, talking, movement, and self-care. It is the pattern across domains over time, not a single lag, that matters. These are signs to check, not a diagnosis; only a qualified clinician can confirm.
Read the answer AnswerEarly Signs of Global Developmental Delay at 6–9 Months
Global Developmental Delay in a 6-to-9-month-old shows as delays across two or more areas together — not sitting or rolling, very floppy or stiff, little babbling, limited eye contact or smiling, and not exploring toys. A single late milestone is rarely a worry; a persistent pattern across areas deserves a friendly developmental check. Only a clinician can assess.
Read the answer AnswerEarly Signs of Global Developmental Delay in a 6-Year-Old
Global Developmental Delay in a 6-year-old shows as several developmental areas lagging together — learning, language, movement and self-care, and social play — across home and school. One area alone is usually a specific delay; multiple persisting delays warrant a structured screening. Only a qualified clinician can confirm what's happening.
Read the answer AnswerEarly Signs of Global Developmental Delay in a 9-to-12-Month-Old
Global Developmental Delay in a 9-to-12-month-old shows as delays across two or more areas together — not sitting by 9 months, no babbling or gestures, limited eye contact or response to name. These are signs to screen, not diagnose; early checks help most.
Read the answer AnswerWhat are the early signs of Global Developmental Delay in a newborn?
Global Developmental Delay cannot be diagnosed in a newborn — development is only beginning and variation is wide. There is no GDD signs list this early. Instead, observe feeding, alertness, muscle tone, response to sound and the first social smile, and keep every routine check-up. Seek prompt review for persistent floppiness, stiffness, poor feeding or no startle to sound; assessment becomes meaningful as milestones emerge in later infancy.
Read the answer AnswerWhat are the early signs of Intellectual Disability?
Intellectual disability shows as slower-than-expected learning across several areas at once — late milestones, delayed speech, difficulty with everyday self-care and simple problem-solving. A pattern of delay across thinking, language and daily living matters more than any single missed skill, and early signs prompt a developmental check, never a label.
