Signs of ADHD in Children: What Should Parents Look For?

This guide explains the common signs parents notice, so you can make sense of what you're seeing at home and decide whether to talk to someone about it.

Children with ADHD often find it hard to control where their attention goes, especially when something feels boring or difficult. You might notice your child:

• seems not to listen when spoken to directly
• finds instructions with several steps hard to follow
• starts tasks but rarely finishes them
• makes careless mistakes, even when they know the work
• loses things every day, like school bags, jumpers or water bottles
• forgets what they were asked to do moments ago
• finds getting ready in the morning a constant struggle

The flip side is that many children with ADHD can focus intensely on things they love, like building, drawing or games, for long stretches. This doesn't mean they can "focus when they want to". Their attention follows interest rather than effort.

Hyperactivity is about energy and movement. You might notice your child:

• is always on the go, as if "driven by a motor"
• finds it really hard to sit still at mealtimes, in class or in the car
• fidgets, taps, wriggles or gets up from their seat
• talks a lot, or finds it hard to play quietly

Impulsivity is about acting quickly before thinking. You might notice your child:

• calls out answers or interrupts conversations
• finds waiting their turn very hard
• grabs things or rushes into situations without noticing danger
• says things that upset others without meaning to

These children are often told off a lot, which can affect their confidence. It helps to remember that they usually aren't choosing to behave this way. Their brain often acts before it has had the chance to pause and think things through.

Emotional differences aren't part of the formal diagnostic criteria, but parents mention them more than almost anything else. Many children with ADHD feel things quickly and intensely. You might notice your child:

• goes from calm to very upset very quickly
• takes a long time to settle after getting upset
• finds small setbacks or changes of plan really hard
• is very sensitive to criticism, or to feeling left out
• gets frustrated easily with tasks that feel hard

These big feelings are real, and they can be exhausting for children and parents. Calm, predictable routines and naming feelings together can help, whatever the cause.

Under 5s: all young children are busy and impulsive, so ADHD is rarely diagnosed at this age. But some parents notice their child is much more active, accident-prone or hard to settle than others the same age.

Primary school: this is when signs often become clearer, as children are expected to sit still, listen and follow instructions. Teachers may mention concentration, calling out or unfinished work.

Secondary school: outward hyperactivity often eases, but organisation becomes harder. Teenagers may struggle with homework, deadlines, timetables and managing their own time. Restlessness can turn inward, and emotional ups and downs can be stronger.

Girls: ADHD in girls is often missed, because it's less likely to be disruptive. Girls may be chatty, quiet or disorganised, and many work hard to hold it together at school, then release all that stress at home.

Strengths: many children with ADHD are creative, curious, funny, energetic and full of ideas. Noticing and building on these is just as important as understanding the challenges.

It's natural to read a list like this and tick off a few things. Most children will show some of these signs some of the time. Tiredness, anxiety, hearing or vision problems, learning differences like dyslexia, autism, or big changes at home can all look similar to ADHD.

A specialist assessment looks at the whole picture: whether the signs stand out compared with other children the same age, have lasted over time, show up both at home and school, and affect your child's daily life. That's something a checklist can't do.

If several of these signs sound familiar and they're making life harder for your child:

• Write down a few real examples of what you notice.
• Ask school whether they see the same things.
• Talk to your GP, who can check for other causes and discuss referral.

You don't need to be sure it's ADHD before asking for help.
