Signs & concerns
When should I worry about genetic syndromes at 12–18 months?
Most toddlers develop at their own pace, but a cluster of signs between 12 and 18 months — significant motor delay, no babbling or words, low muscle tone, feeding difficulties or distinctive physical features — is worth a closer look. Many genetic syndromes are found before birth; some become clearer as development unfolds. Only a clinician, usually starting with your paediatrician, can assess what's underneath.
Read the answer AnswerWhen should I worry about Global Developmental Delay at 12–18 months?
Worry is reasonable if your 12-to-18-month-old shows delays in two or more areas — movement, speech, social or thinking skills — or loses skills they once had. A single slow area is often normal; a pattern is the flag to check. Only a clinician can confirm GDD.
Read the answer AnswerWhen to worry about Gross Motor Delay at 12–18 months
By 12–18 months most toddlers pull to stand, cruise and begin walking, but the normal range is wide and walking can arrive up to about 18 months. Ask a clinician if your child isn't sitting or weight-bearing by 12 months, isn't walking by 18 months, has lost a motor skill, or always favours one side. Early checks bring reassurance and, where useful, a head start.
Read the answer AnswerWhen should I worry about hearing impairment at 12-18 months?
By 12–18 months, check with your doctor if your child doesn't turn to sounds, isn't babbling or saying any words, or doesn't respond to their name — especially if responsiveness has faded. This needs a hearing check, not panic. Only a clinician can confirm; early checks help enormously.
Read the answer AnswerWhen should I worry about hypotonia at 12–18 months?
Between 12 and 18 months, low muscle tone is worth a prompt check if your toddler isn't pulling to stand or cruising by ~12–14 months, isn't walking by 18 months, feels limp or slips through your hands when lifted, or tires quickly and sits with a very rounded back. Hypotonia is a finding, not a diagnosis — a clinician assesses the whole picture, finds any cause, and supports movement with gentle therapy.
Read the answer AnswerWhen should I worry about Intellectual Disability at 12–18 months?
At 12–18 months it is too early to diagnose Intellectual Disability — this is a watch-and-support stage, not a labelling one. Track the overall pattern across play, communication and movement; a persistent lag across several areas, or loss of skills, is a reason for a friendly developmental check. Only a clinician can assess, and meaningful assessment comes later.
Read the answer AnswerWhen should I worry about motor planning at 12–18 months?
At 12–18 months motor planning is still developing, so there is wide normal variation. Worth a relaxed developmental check — not panic — if a toddler isn't walking by ~18 months, rarely tries new movements, seems markedly clumsy, or loses a motor skill they had. These are signals to observe and ask, never to diagnose at home; a true diagnosis comes later when more complex movement is expected.
Read the answer AnswerWhen to Worry About Few Words at 12–18 Months
At 12 to 18 months a wide range of talking is normal, and a non-verbal or minimally verbal presentation is not a diagnosis at this age. What matters most is connection — pointing, gestures, responding to name and shared looks — not word count. Worth a check if there are no gestures by 12 months, no response to name, little babble, no shared attention, or any loss of skills.
Read the answer AnswerWhen to worry about ODD in a 12–18-month-old
Oppositional Defiant Disorder is not a meaningful diagnosis at 12–18 months — saying "no", tantrums and refusals are expected toddler development as your child discovers they are a separate person. ODD (ICD-11 6C90) is recognised only from the preschool years, once the brain can self-regulate. At this age, watch communication, connection and play rather than "defiance", and seek a gentle check if those foundations seem delayed. Only a Pinnacle clinician can assess — never an online form.
Read the answer AnswerToe-Walking at 12–18 Months: When to Worry
Between 12 and 18 months, occasional toe-walking is very common and usually harmless as new walkers find their balance — it is too early to call it persistent. Worry only if your child can never put their heels flat, the calves feel tight, it is one-sided, or there are other developmental delays. A clinician can gently rule out any underlying cause.
Read the answer AnswerWhen to worry about prematurity-related developmental risk at 12–18 months
For toddlers born prematurely, always judge milestones by corrected age (from the due date) up to about two years. With that adjustment, most catch up well. Seek a developmental check if, by corrected 12–18 months, your child isn't pulling to stand or walking with support, isn't babbling or using first words, shows little pointing or shared interest, or seems stiff or floppy on one side. Only a clinician can assess.
Read the answer AnswerWhen to worry about Rett Syndrome at 12–18 months
Rett Syndrome is rare and almost always affects girls, with typical early development followed by a slowing or loss of skills, usually between 6 and 18 months. In the 12–18 month window the signal to act on is regression — losing hand skills or words she once had, repetitive hand movements, slowing head growth or new unsteadiness — not a single delayed milestone. Because it has a genetic basis, any suspected loss of skills warrants a prompt paediatric and developmental review. A diagnosis is formed only at a Pinnacle centre under clinician care, never from a checklist.
Read the answer AnswerWhen to worry about School Readiness Gap at 12–18 months
School readiness is not measured in a 12-to-18-month-old — it is a picture that forms years later, around ages 4 to 6. At this age the right focus is the broad developmental foundations: communicating, connecting and exploring. A true School Readiness Gap cannot be identified this young; review with a clinician if general milestones are delayed.
Read the answer AnswerWhen to Worry About Selective Mutism at 12–18 Months
Selective Mutism is not assessed in a 12-to-18-month-old. It describes a child who speaks freely in some settings but consistently not in others — a pattern recognisable only once a child has reliable speech and regular social exposure, usually from around age 3. At this age, quietness with strangers is normal caution. Watch communication building blocks — babbling, gestures, first words, responding to name — and seek a general check if these are absent by 18 months. Only a Pinnacle clinician can assess, never an online form.
Read the answer AnswerWhen should I worry about self-regulation at 12–18 months?
At 12–18 months, intense feelings, tantrums and needing help to calm down are normal — toddlers rely on co-regulation with a caring adult, and self-regulation develops years later. There is no self-regulation disorder to diagnose at this age. Worth a gentle developmental check are persistent inconsolability, no comfort-seeking, extreme sensory overwhelm, or loss of skills once gained.
Read the answer AnswerWhen should I worry about feeding selectivity at 12–18 months?
Between 12 and 18 months, a phase of food refusal (neophobia) is normal and time-limited. Worry — and seek a gentle check — when refusal is persistent and sensory-driven (about texture, smell or look), narrows the diet to very few foods, or affects growth and family wellbeing. Rule out medical causes with your paediatrician first; only a Pinnacle clinician can assess, never an online form.
Read the answer AnswerWhen should I worry that my 12-to-18-month-old might have Sensory Processing Differences?
At 12–18 months, sensory likes and dislikes are normal and we watch patterns rather than diagnose. Worry sooner if intense, lasting distress with sound, touch or movement disrupts eating, sleep or play — and rule out hearing first. Only a Pinnacle clinician can confirm anything.
Read the answer AnswerSeparation Anxiety at 12–18 Months: When to Worry
Crying and clinging at 12–18 months is a normal, healthy attachment milestone — not Separation Anxiety Disorder, which is rarely meaningful at this age. The reassuring marker is recoverability: a securely attached toddler settles with a familiar carer. Consider a routine developmental check only if distress is relentless across days and settings, never eases with any comforting, or affects feeding, sleep or skills. Only a Pinnacle clinician can assess, never an online form.
Read the answer AnswerWhen Should I Worry About Social Communication at 12–18 Months?
At 12–18 months, Social Communication Difficulties is not formally diagnosed, but this is a key window to gently observe how your toddler connects — name response, eye contact, pointing, gestures and babble. A persistent pattern of several missed social-communication behaviours, or loss of skills once present, deserves a friendly developmental check rather than waiting. Only a Pinnacle clinician can assess; never an online form.
Read the answer AnswerWhen should I worry about SLD in a 12-to-18-month-old?
Specific Learning Disability is about reading, writing and maths — skills that haven't begun at 12–18 months, so it can't be identified or worried about this early. It usually becomes clear around ages 6–8. For now, watch broad milestones like babbling, pointing, understanding and walking; a persistent pattern of several delays is reason for a general developmental check, not a label.
Read the answer AnswerWhen should I worry about speech delay at 12–18 months?
At 12–18 months, range is wide and one quiet talker is rarely cause for alarm. Worry becomes meaningful with a pattern: no babble or gestures by 12 months, no words by 15–18 months, no understanding of simple requests, or loss of skills once gained. A check — starting with hearing — is the hopeful next step; only a clinician can tell delay from a phase.
Read the answer AnswerWhen should I worry about Stereotyped Movement Disorder at 12–18 months?
Rocking, hand-flapping and rhythmic movements are common and usually harmless in 12-to-18-month-olds. Stereotyped Movement Disorder (ICD-11 6A06) is considered only when movements are persistent, purposeless, hard to interrupt, cause self-injury, or come with other developmental concerns. At this age the right stance is watchful observation, not diagnosis — and only a Pinnacle clinician can assess.
Read the answer AnswerWhen should I worry about Tourette Syndrome in a 12–18-month-old?
Tourette Syndrome cannot be meaningfully identified at 12–18 months — it is recognised only when motor and vocal tics persist beyond a year, typically from age 4–8. Toddlers' repetitive blinks, sounds and movements are almost always normal exploration, not tics. The right step now is a warm general developmental check, and only a Pinnacle clinician can assess, never an online form.
Read the answer AnswerWhen to worry about vision in a 12–18 month old
By 12–18 months most toddlers make eye contact, follow moving objects, reach accurately and point. Worry — and seek a prompt check — if your child consistently avoids eye contact, holds things very close, has wandering or wobbling eyes, bumps into things, or shows little interest in faces and pictures. These are observations to act on, not a diagnosis; only a Pinnacle clinician can assess vision properly, never an online form.
