What ADHD can look like in children
- Finding it hard to sit still
- Fidgeting, climbing or moving constantly
- Talking a lot or interrupting others
- Acting before thinking, struggling to wait their turn
- Becoming distracted very easily
- Losing things and forgetting instructions
- Daydreaming or appearing not to listen
- Avoiding homework or tasks
- Having big emotional reactions and becoming overwhelmed quickly
- Struggling with friendships and transitions
- Needing lots of reminders and struggling with routines
- Making careless mistakes, starting tasks but not finishing them
Some children are very obviously hyperactive. Others are quieter and may seem dreamy, anxious, disorganised or emotionally sensitive. This is one reason ADHD can sometimes be missed, especially in girls.
Attention
Attention difficulties don't always mean a child cannot focus at all. Many children with ADHD can focus deeply on things they love — gaming, drawing, animals, history, music, Lego, YouTube, sport or a favourite subject. This is sometimes called hyperfocus.
The difficulty is often with controlling attention. A child may find it very hard to focus on something that feels boring, too hard, too easy, repetitive, overwhelming or not immediately rewarding.
They may:
- Focus brilliantly on preferred interests
- Struggle to start non-preferred tasks
- Become distracted by sounds, thoughts, people or objects
- Forget what they were doing halfway through
- Need instructions repeated or broken into smaller steps
- Feel overwhelmed by too much information at once
This does not mean they are ignoring adults on purpose — their brain may simply be struggling to filter, organise and hold information.
Hyperactivity
Hyperactivity can look like running, climbing, jumping, fidgeting constantly, rocking on chairs, talking excessively, always needing to move or struggling to sit through meals, lessons or appointments.
Some children are physically hyperactive. Others feel hyperactive inside — like their thoughts are racing even if their body looks still. Movement isn't always the problem; sometimes movement helps the child regulate, focus and stay calm.
Helpful support: movement breaks, fidget tools, active learning, short tasks, outdoor time, and not expecting a child to sit still for long periods without support.
Impulsivity
Impulsivity means acting, speaking or reacting before the brain has had enough time to pause and think. A child may shout out answers, interrupt, grab items, run ahead, take risks, say things that sound rude, or react quickly when upset and regret it later.
Impulsivity is not simply "naughtiness". It is linked to brain development, self-control and emotional regulation. Children need teaching, support and practice — not shame. Calm reminders, clear boundaries, visual cues, practice scripts and praise for pausing all help.
Emotional regulation
Many children with ADHD feel emotions very strongly. They may go from calm to upset very quickly and react intensely to things that seem small to others — meltdowns, anger, crying, shouting, refusing, running away, hiding or shutdowns, often followed by shame.
The child isn't trying to be difficult. Their nervous system may be overloaded and their brain may struggle to slow emotional responses.
What helps: staying calm, reducing demands, using fewer words, giving space, validating feelings, offering choices, using visual supports, teaching calming strategies when the child is already calm, and repairing afterwards without shame.
