Why Does My ADHD Child Forget What I Just Said?

The short answer: a child with ADHD isn’t lazy, and isn’t excused either. Give one instruction at a time, close by, and check it landed.

You send your child upstairs for shoes, and five minutes later find them reading a comic. “What shoes?”

It is one of the most common frustrations in families living with ADHD. My view: a child with ADHD is not lazy, and is not excused either. The forgetting is real. So is the responsibility. Our job is to move the help out of our voice and into the world, and then, step by step, hand it to the child. Here are the questions parents most often ask.

Are they just not listening?

Often, they did listen. The words went in. What may be harder is holding them in mind long enough to act on them, especially when something more interesting appears on the way.

Russell Barkley, a leading ADHD researcher, describes the core difficulty as “not one of knowing what to do but one of doing what you know” (Barkley 1997). Your child knows about the shoes. The knowing just slips away before it reaches the hands.

Is it laziness, or that they don’t care?

Very rarely. Many children with ADHD care a great deal, and are ashamed when they forget again. Being told “you never listen” hundreds of times can leave a child feeling that something is wrong with them, not just with the shoes.

ADHD often comes with real difficulty steering emotions, too (Shaw and colleagues 2014). So when a forgotten instruction leads to a scolding, the reaction can be much bigger than the shoes, because it touches all the other times.

Will saying it louder or more often help?

Usually not much. Repeating the instruction adds more words to a place where words are not the problem. Many families find the repetition mostly raises the temperature in the house.

So what does help?

Ideas that tend to help move the reminder out of the air and into the world, where the task happens.

• One instruction at a time. “Shoes” first. Coat after the shoes are on.
• Short and specific. “Shoes on, by the door” rather than “Get ready to go out.”
• Get close and get eye contact first. Say their name, wait for them to look, then speak. Calling from another room rarely works.
• Ask them to say it back. “What are you going upstairs for?” “Shoes!” It costs two seconds and can double the chance it sticks.
• Write it where it happens. The UK’s ADHD guideline gives “reinforcing verbal requests with written instructions” as an example of a helpful change (NICE NG87). A picture card on the bedroom door for younger children, a note or phone reminder for older ones.
• Put things where they will be needed. Shoes by the front door, not upstairs.

Barkley calls this putting help at the “point of performance”: the exact place and moment the task must be done (Barkley 2019, presentation).

Why does it seem worse on some days?

Many parents notice that forgetting gets worse on certain days: after a bad night’s sleep, at the end of a long school day, when the house is noisy, or when the child is anxious about something else. ADHD does not switch on and off, but tiredness, stress and hunger can make it harder to manage. Keeping an eye on these patterns can help you plan: fewer instructions on hard days, more written cues, and more patience for both of you.

Sleep matters for every child. School-age children need nine to twelve hours, and teenagers eight to ten (Paruthi and colleagues 2016).

Should I use a reward chart?

For younger children, simple rewards linked to specific tasks can help. For teenagers, the American Academy of Pediatrics notes that they “can often effectively obstruct behavioral contracts, increasing parent-adolescent conflict” (AAP 2019 guideline). With teens, plans they help to build tend to work better than plans built for them.

Is it my fault if it isn’t working?

No. These ideas reduce the gap; they rarely close it completely. ADHD is a real difference in how attention and memory work, not a parenting failure. If daily life is very hard, the clinician who supports your child’s ADHD can suggest more help, at home and at school.

When should I talk to a doctor?

If you think your child may have ADHD but has not been assessed, talk to their doctor. If your child is already being treated, tell the prescribing doctor about any changes in sleep, appetite or mood (NICE NG87). If your child seems persistently low, anxious, or talks about being stupid or worthless, mention it too. If your child talks about wanting to die or to hurt themselves, reach a doctor or crisis service today. If someone is in danger now, call your local emergency number.

One small step

Choose the instruction that most often gets lost in your house. Shoes, teeth, schoolbag, anything.

For the next five days, give it the “three-step” way: say their name and wait for eye contact, give the instruction in five words or fewer, then ask them to say it back. Add a written cue where the task happens.

Each evening, note how many times you had to repeat it, and how the moment felt. By Friday, you may find the instruction still slips sometimes, but the house is calmer. For many families, that calm is the first real step.

Next step

Try one week of saying it once. Answer a few questions about what keeps slipping, and get a 7-day sheet built for your child. Remind once →
