How do I keep calm when my child insists they know everything and I say no? 

Parenting Perspective 

When your child crosses their arms and declares, ‘I already know that!’ after you have offered guidance or refused a request, it can be deeply frustrating. It is easy to think that they are too young to act with such an attitude. However, what you are witnessing is often not arrogance, but a developmental expression of independence. As children grow, they naturally crave a sense of control and competence. When you say no, their response of ‘I know everything’ is often a way of protecting their pride, not attacking your authority. How you handle this moment will determine whether it becomes a power struggle or a valuable lesson in humility. 

Understanding What Lies Beneath ‘I Know Everything’ 

At its core, this behaviour is about self-esteem and autonomy. Children want to feel capable and trusted. When they hear a correction or a ‘no’, they can interpret it as a message that you do not have faith in them. Their insistence that they ‘know everything’ is a shield, a defence against feeling embarrassed or vulnerable. Viewing it from this perspective allows you to respond with empathy instead of irritation. 

Grounding Yourself Before Responding 

Before you react, it is important to pause. Take a slow, steadying breath and remind yourself: this is a sign of immaturity, not disrespect. When you emotionally detach from the comment, you can find the calmness needed to respond wisely. Your goal is to guide your child, not to win an argument with them. 

A Calm and Respectful Script 

Here is how you can respond calmly when your child insists they ‘already know’ after you have said no: 

• Acknowledge their confidence: ‘It is good that you feel so sure of yourself. I can see you are learning to think for yourself, and that is very important.’ 

• Hold your boundary with respect: ‘However, even when we know a lot, we still need to listen. Everyone, including adults, has more to learn.’ 

• Reinforce the purpose of your ‘no’: ‘My decision is not about what you know. It is about what is safe and right for our family right now.’ 

• End with connection: ‘You are a smart child, and I respect your thinking. Let us try to work together on this instead of arguing.’ 

These words affirm your child’s growing independence while preserving your parental authority. You are showing them that confidence is welcome, but that humility and respect must grow alongside it. 

Handling a Continued Argument 

If your child becomes defensive or continues to argue, resist the temptation to correct their every word. Instead, calmly state, ‘I am not going to argue about this. My answer is still the same. When you are ready to speak kindly, I will be ready to listen.’ Then, gently disengage from the conversation. Your calm silence can end a power struggle more effectively than any lecture. 

Reflection After the Moment 

Later, when things have settled, you can reflect on the incident together. You might say, ‘I know you feel you understand a lot of things already, and that is a good thing. But learning is a journey that never ends, even for me. When we listen to each other with respect, we both grow stronger.’ This helps your child to associate humility with strength, not weakness. 

Spiritual Insight 

Staying calm when your child insists they ‘know everything’ is a reflection of a core Islamic character trait: sabr (patience) combined with hikmah (wisdom). While Islam honours the pursuit of knowledge, it also warns against arrogance, reminding us that true wisdom lies in humility. When you respond to your child’s pride with gentleness, you are teaching them that learning is a lifelong journey guided by respect for others and for the truth. 

Humility and Knowledge in the Quran 

The Quran powerfully reminds us that no matter how much we learn, our knowledge is insignificant compared to the infinite wisdom of Allah Almighty. 

Allah Almighty states in the noble Quran at Surah Al Israa (17), Verse 85: 

‘And they question you (O Prophet Muhammad ﷺ), matters pertaining to the Spirit (containing Information Codes of Existence); say to them: “The Spirit (containing Information Codes of Existence is directly connected) with the commandments of my Sustainer; and you have not been bestowed with the knowledge (to understand the realities of this connection) except a very limited amount”.’ 

This verse humbles every human being. By calmly holding your ground, you are showing your child that true wisdom is not about having all the answers, but about knowing when to listen and learn. 

The Prophet’s ﷺ Example of Teaching with Patience 

The Prophet Muhammad ﷺ taught that humility is a source of honour and that Allah raises the status of those who practise it for His sake. 

It is recorded in Sahih Muslim, Hadith 2588, that the holy Prophet Muhammad ﷺ said: 

‘No one humbles himself for the sake of Allah except that Allah raises him in status.’ 

This Hadith perfectly illustrates how humility leads to honour. The Prophet ﷺ guided his companions with gentleness, never shaming their pride. When you respond to your child’s insistence with calmness, you are modelling that same prophetic approach, teaching that respect elevates knowledge far more than self-assertion ever could. 

When your child claims to ‘know everything’, your calm response becomes their lesson in emotional maturity. You are showing them that knowledge without good manners loses its light, and that wisdom shines brightest through patience. 

Each time you remain composed, you help your child see that learning and listening walk hand in hand. Over time, they will understand that your calm ‘no’ was not an act of opposition, but one of guidance, a quiet reflection of a love that taught them how to pair confidence with humility, and intellect with grace.
