ADHD Symptoms in Kids: What to Look For

Last updated 24 October 2026 · 13 min read · By Sarah M., Support Coordinator
In short

ADHD symptoms in kids fall into two groups: inattention, such as losing focus and forgetting things, and hyperactivity-impulsivity, such as constant movement and acting before thinking. Only a trained health professional can diagnose a child, so this guide is for parents, carers and families who want to understand what to look for and where to go next. It covers signs by age, causes, activities, school supports and funding in Australia.

Key points

  • Around 6-8% of children and 3-5% of adults in Australia have ADHD, according to the Australian ADHD Guideline.
  • Under DSM-5, a child needs 6 of 9 inattentive symptoms or 6 of 9 hyperactive-impulsive symptoms to reach the diagnostic threshold.
  • Only health professionals with special training can diagnose a child, and many GPs refer families to a paediatrician, child psychologist or child psychiatrist.
  • The Australian ADHD Guideline says ADHD is highly heritable in children and adults, with heritability estimated at 70-80%.

What is ADHD in children?

ADHD stands for attention deficit hyperactivity disorder. The Australian ADHD Guideline’s GP factsheet says around 6-8% of children and 3-5% of adults in Australia have ADHD (AADPA).

ADHD symptoms in kids: inattention and hyperactivity

Under DSM-5, there are 9 inattentive and 9 hyperactive-impulsive symptoms, and for children 6 of the 9 in a group must be present to reach the diagnostic threshold (AADPA).

Symptom groupWhat it can look like in a child
AttentionMakes careless mistakes, drifts off mid-task, loses pencils and shoes, and seems not to listen when spoken to
OrganisationStruggles to start homework, forgets lunch boxes and notes, and finds multi-step instructions overwhelming
ActivityFidgets, leaves their seat, climbs at the wrong time and talks non-stop
Impulse controlBlurts out answers, interrupts games, grabs things and finds it hard to wait in line

A diagnosis also needs evidence that symptoms started before age 12, lasted at least 6 months and cause impairment in at least two settings, such as home and school (AADPA).

Signs of ADHD in children at home and at school

Use these lists as a prompt for a conversation with your GP, not as a way to label your child. Only a qualified professional can assess this.

  • Starts a game, puzzle or chore with enthusiasm, then moves to something else before finishing and leaves a trail of half-done projects.
  • Loses belongings such as hats, drink bottles and school books again and again, even after reminders and a set place for them.
  • Gets up from the table, the mat or the car seat constantly, or seems to be driven by a motor.
  • Calls out in class, interrupts adults and finds it very hard to wait for a turn in games.
  • Struggles to keep track of the steps in a morning routine, such as getting dressed, eating breakfast and packing a school bag.
  • Avoids or puts off tasks that take sustained mental effort, such as homework, reading practice or tidying a bedroom.

Some children show these signs in some places and not others. If your child holds it together at school and falls apart at home, mention that to the professional. If you are also wondering about autism, see our guide to signs of autism in children as well.

ADHD symptoms in kids by age

Symptoms change as children grow, and expectations at school change with them. These examples show what families often notice, not what any child must show.

ADHD in a 5 year old

The Royal Children’s Hospital says children usually must be at least about five years old for an assessment. Before that, the Australian ADHD Guideline recommends parent and family training for families of children younger than 5, because medication is not routinely offered in this age group (AADPA).

  • Seems unable to sit for story time or circle time, even when the story is one they enjoy.
  • Runs ahead in car parks and shops, and does not stop when called, which can be a safety worry.
  • Has very big reactions to small disappointments, such as losing a game or leaving the park.

7 year old ADHD symptoms

As schoolwork increases, families and teachers sometimes describe signs like these.

  • Rushes through written work with many mistakes, or takes a very long time to start it.
  • Forgets instructions given a moment ago and needs them broken into one step at a time.
  • Struggles with playground rules, takes things personally and has trouble keeping friendships steady.

Older children and teenagers

For older children and teenagers, a diagnosis still needs evidence that symptoms started before age 12. Under DSM-5, people aged over 17 years need only 5 symptoms rather than 6. For younger children, the AIHW reports ADHD was present in 10.9% of boys, 5.4% of girls and 8.2% of all children aged 4-11 in 2013-14 (AIHW). For signs in girls, read our guide to ADHD in girls.

How do you know if your child has ADHD?

You cannot be sure from a checklist or quiz, but you can take clear steps towards an assessment. Our guide to the ADHD test for kids explains what to expect.

  1. Write down what you see over a few weeks. Note what happens, where, when and how often, including the good moments and your child’s strengths.
  2. Ask the teacher for examples. Because symptoms must cause impairment in at least two settings, school observations are very useful evidence.
  3. Book a GP appointment. Bring your notes, school reports and any questions, and ask the GP what else might explain what you are seeing.
  4. Ask about a referral. Only health professionals with special training can diagnose children, and many GPs refer families to a paediatrician, child psychologist or child psychiatrist (Royal Children’s Hospital).
  5. Attend the assessment together. Expect questions about development, behaviour, family history and school, and ask for any recommendations in writing.

What causes ADHD in children?

Research points mainly to genes, with some environmental factors that may contribute.

  • The Australian ADHD Guideline says ADHD is highly heritable, with heritability estimated at 70-80%, and that 12 independent genomic loci increase susceptibility.
  • healthdirect states genetic studies show ADHD is an inherited disorder.
  • Environmental factors that may contribute include premature birth, low birth weight and lead exposure (healthdirect).
  • healthdirect also lists maternal smoking or drinking during pregnancy and early childhood trauma as possible contributors.

If your family history includes ADHD, tell the assessing clinician.

ADHD activities for kids: games and activities for children with ADHD

The Australian ADHD Guideline found very few, small, low to very low quality studies on lifestyle changes, made no specific recommendations, and continues to support advice on a balanced diet, good nutrition and regular exercise (AADPA). Activities are about enjoyment, movement and routine, not treatment.

Activity typeExamplesWhy families like it
Active playSwimming, bike riding, obstacle courses, trampolines, martial arts and dancePlenty of movement, in line with general advice on regular exercise
Short-turn gamesSimon says, freeze dance, charades and quick card gamesTurns are short, so waiting is easier
Hands-on makingBuilding blocks, clay, cooking together and craft with clear stagesClear stages and a finished result
Calm-down timeStretching, listening to music, drawing and quiet reading cornersOffers a predictable way to reset after school

Some families find games for kids with ADHD easier to enjoy when rules are short and a visual timer or checklist is nearby. Our guide to ADHD books for kids lists stories you can read together.

Support for ADHD in children at school and home

The Australian ADHD Guideline recommends that parent and family training be offered to parents and carers of children and adolescents with ADHD (AADPA). Talk to your GP, paediatrician, psychiatrist or pharmacist about any medicine questions.

Help your child at school

Students with ADHD are protected by the Disability Standards for Education (2005), part of the Disability Discrimination Act (1992). They require education providers to consult, make reasonable adjustments and eliminate harassment (AADPA). Our guide to ADHD classroom strategies covers seating, instructions and movement breaks.

Support an ADHD child at home

Our guide to parenting a child with ADHD covers routines, rewards and calm responses. These habits are a good starting point:

  • Give one instruction at a time, with eye contact, and ask your child to repeat it back.
  • Use a visual routine chart for mornings and bedtime so you are not the constant reminder.
  • Notice and name what goes well, as well as what needs work.
  • Plan movement before homework, and keep homework sessions short with a clear finish line.

Treatment options

Options are decided with your child’s clinician and can include parent training, school adjustments and, for some children, medicine. Our guide to ADHD treatment explains the options in Australia, including how adults are supported.

ADHD government benefits in Australia for a child: ADHD symptoms in kids and the NDIS

The NDIS can fund supports only if your child meets the NDIS access requirements, and each family’s situation is different. Check with the NDIA and Services Australia for current rules and payments.

  • ADHD is not on the NDIA’s List A or List B access lists, but the NDIA told the Senate inquiry that this “doesn’t preclude anyone with ADHD testing access to the scheme”.
  • As at 31 March 2023, 188 NDIS participants had ADHD as their primary disability and 4,676 had it as a secondary disability, 4,864 in total (Parliament of Australia).
  • The Senate inquiry report notes that some participants list ADHD as their sole disability.
  • Bring reports from your paediatrician, psychologist or occupational therapist and your diary of daily support needs to any planning or access meeting.

When to talk to a GP about ADHD symptoms in kids

  • Your child’s attention or energy makes learning, friendships or family routines hard on most days.
  • Teachers have raised the same concerns across more than one term or more than one year.
  • Your child is often very upset, anxious or low in mood, or sleep is a regular struggle.
  • Safety is a worry, such as running onto roads or leaving school grounds.
  • You are exhausted and unsure how to support them, and want advice for the whole family.

Call 000 in an emergency. If you or someone in your family is in crisis, call Lifeline on 13 11 14, or 000 if someone is in immediate danger. The ADHD Foundation, listed by healthdirect on 1300 39 39 19, offers ADHD support for families.

Common questions

FAQs about ADHD in children

What causes ADHD in children? +

The Australian ADHD Guideline says ADHD is highly heritable, with heritability estimated at 70-80%. healthdirect says premature birth, low birth weight, lead exposure, maternal smoking or drinking in pregnancy and early childhood trauma may also contribute. Your child’s clinician can talk you through what is known about causes.

How do you know if your child has ADHD? +

You cannot tell for certain at home. Watch for patterns that last at least 6 months, appear in more than one setting and affect daily life, then book a GP visit. A paediatrician, child psychologist or child psychiatrist can make an assessment and, if needed, a diagnosis.

How do I stop my ADHD child swearing? +

Impulsive words often come out when a child is excited or frustrated. Stay calm, name the feeling, and tell them what to say instead. Praise the moments they choose a different word, and agree on a simple rule at home so everyone responds the same way.

How do I calm down a child with ADHD? +

Lower your voice, reduce noise and offer a quiet space, a drink or a short walk before talking about what happened. Practise calming steps when things are peaceful, so they are familiar when needed. If big reactions happen often, mention them to your GP or paediatrician.

How do I explain ADHD to a child? +

Use simple, positive words: their brain works a bit differently, which makes some things harder and others, like creativity and energy, a real strength. Use age-appropriate stories, answer questions honestly and tell them it is not their fault and that you are on their team.

How can I reduce impulsivity in an ADHD child? +

Short, predictable routines, clear rules and a warning before changes help. Practise pausing in games like freeze dance, and praise waiting or thinking first. Discuss strategies with your child’s clinician or school, since parent and family training is recommended for families of children with ADHD.
