When Your Child Says “I Don’t Know”: What It Can Really Mean

You ask what happened at school, why a friend was upset or how to solve a homework question. Your child replies, “I don’t know.” It can be tempting to hear this as avoidance, especially when you believe they know the answer.

Sometimes a child genuinely does not know. At other times, the question may be unclear, the words hard to find, the memory difficult to organise or the conversation uncomfortable. “I don’t know” is a starting point for understanding, not a reliable sign of laziness, defiance or a particular condition.

What does answering a question involve?

A child must notice the question, understand its meaning, recall relevant information, organise an idea and put it into words. Questions about feelings also require recognising an internal experience and choosing how to share it. Difficulty at any point can make answering harder.

Being good at building, reading or mathematics does not mean that every speaking task will feel easy. Equally, a slow answer does not automatically mean a language disorder. The pattern and its impact matter more than a single pause.

What might “I don’t know” mean in this moment?

“The question is too big”

“How was school?” asks a child to search an entire day and decide what matters. A smaller invitation may be easier: “Tell me one thing you did at lunchtime.” Questions about “why” can also be difficult when a child cannot yet explain motives or feelings.

“I need more time or a way to organise my answer”

A child may remember fragments without knowing where to begin. A drawing, a photo or a simple “first, next, last” prompt can offer a starting point. These supports help communication; they do not prove what caused the difficulty.

“I understand, but the word is not coming”

Word finding means retrieving a word you know when you need it. A child may use “that thing,” describe what an object does or pause before naming it. However, word finding, understanding language, speech-sound production and rapid naming tasks are not interchangeable. A proper evaluation considers the broader communication picture.

“I’m worried about being wrong—or not ready to talk”

Repeated correction or pressure for a quick answer may make a conversation feel like a test. Some children find feelings difficult to name; others want privacy or need a break. A child may also have lost track of the question or simply not learned the answer yet. More than one explanation can apply.

How can I respond without adding pressure?

Pause before asking again

Allow a comfortable silence. Avoid repeating the question more loudly or firing off several alternatives. There is no universal number of seconds that separates ordinary hesitation from a clinical difficulty.

Make one question concrete

Instead of “Why did you do that?”, try “What happened just before?” Instead of several questions about school, choose one familiar moment. If the child seems unsure of the wording, rephrase rather than testing the same question again.

Offer another route to an answer

“Would you like to show me, draw it or tell me later?” With younger children, pictures or objects may help. With an older child, a written note may feel easier. Offer choices without steering the child towards the answer you expect, and accept “something else” or genuine uncertainty.

Make uncertainty acceptable

Try: “It’s okay not to know. Let’s work out what part is confusing.” During homework, check whether the concept needs teaching before expecting an explanation. Praise the child for clarifying a question or asking for help, rather than only for answering quickly.

For an everyday conversation, you might say: “We don’t have to talk about the whole day. I’m here if there’s something you want to share.” Respect a pause while staying curious about persistent distress.

What changes in a multilingual Hong Kong family?

A child may learn school vocabulary in English, use Cantonese with family and speak Mandarin in another setting. Familiarity with a topic can differ between languages. Allow the child to use the language, gesture or combination of languages that helps them communicate.

Multilingualism itself does not cause a language disorder. If concerns persist, evaluation should consider language exposure, use and skills across the child’s languages, rather than judging ability from one brief English response. Do not assume every difficulty is “just bilingualism,” either.

What should parents and teachers observe?

Compare contexts: does answering become easier with extra time, a familiar adult, visual support or a more familiar language? Is the difficulty mainly recalling events, understanding instructions, explaining feelings or speaking in a group?

Share specific examples: “They could show the solution, but struggled to explain it,” is more useful than “They never answer.” Ask teachers what supports already help. A response to a strategy offers clues, not a home diagnosis.

When should I seek professional advice?

Consider advice when difficulties are persistent, cause significant frustration or affect classroom participation, friendships or everyday communication. Concerns about understanding instructions, frequent difficulty finding familiar words, or consistently avoiding speaking also deserve discussion. A marked loss of communication skills warrants prompt professional attention.

A speech and language therapist can examine understanding and expression; a psychologist may help when anxiety, attention, learning or broader developmental concerns are involved. Hearing concerns should also be raised with an appropriate professional. The starting point should match the difficulty, not a label inferred from “I don’t know.”

Sprout in Motion in Wong Chuk Hang, Hong Kong, Central and Tsim Sha Shui in Hong Kong provides speech and language therapy and psychological services. A consultation can help families decide what support or assessment, if any, is appropriate.

Questions parents often ask

Is my child being uncooperative?

Possibly, but this phrase alone cannot tell you. First consider understanding, task difficulty, timing and emotional comfort.

Should I always provide the answer?

No. Offer enough support to help your child participate, and reduce it as they manage. Sometimes the next step is teaching, rest or a later conversation.

A useful change is to ask: “What would make this question easier to answer?” That keeps the focus on communication and gives the child a way forward.
