Quick answer: the why phase is a child discovering that things have causes, and that you are the search engine. It usually peaks between three and five. Answering well matters less than answering warmly, and the best response is often another question.

There is a particular kind of tired that only comes from being asked why forty times before breakfast. Why is the sky like that. Why does the bus stop. Why do I have to. Why. Why. Why.

It is genuinely wearing, and it is also one of the most encouraging things a small child can do.

What is actually happening in there

Somewhere around three, children work out something enormous: events are not random. Things happen because other things happened. Cause and effect.

Once a child has that idea, the entire world becomes a set of unopened boxes, and they have discovered that there is an adult nearby who can open them. The questions are the sound of a mind building a model of how the world works.

Three things are going on at once, and it helps to know which one you are dealing with:

  • Genuine curiosity. They want to know. These are the questions with a real puzzled face attached.
  • Conversation. Sometimes why simply means "keep talking to me." The content is not the point, the connection is.
  • Delay and negotiation. Why do I have to put my shoes on. This one is not curiosity, and treating it as curiosity will keep you at the door for twenty minutes.

Why it is worth protecting

Curiosity is not a fixed trait. It is a habit that is either encouraged or quietly trained out.

A child who learns that questions are welcome becomes an adult who asks them. A child who learns that questions are an inconvenience gets very good at not asking, which looks like good behaviour and costs a great deal. By the time they hit primary school, we very much want a child who puts a hand up when they do not understand.

There is also a language dimension. Children learn most of their vocabulary through conversation with adults, not from being taught words. Every why is an invitation to a longer, richer exchange than you would otherwise have had.

How to answer, when you have the energy

Give it back first. "That is a good one. What do you think?" This is not dodging. Children this age have theories, and their theories are wonderful. It also turns a one-way question into a real conversation.

Answer honestly and simply. You do not need a full explanation. One accurate sentence in words your child knows is better than a lecture. Precision matters less than not making something up.

Say when you do not know. "I have no idea. Let us find out." This is one of the most valuable sentences a parent can model. It teaches that not knowing is normal and that finding out is a thing people do.

Go and look. Where you can, make the answer physical. Go outside and look at the moon. Put the ice cube in the sun and come back later. A four-year-old learns far more from watching something happen than from being told about it.

Follow the passion. If the questions are all about diggers, buy the digger book. Deep interest is how young children learn to concentrate, and the subject matters much less than the depth.

How to answer when you have nothing left

You will not always have the energy, and pretending otherwise helps nobody.

  • Be honest about it. "I love your questions. My brain is tired. Ask me again after dinner." Then actually let them.
  • Bank it. Keep a question list on the fridge and look one up together at the weekend. Children love seeing their own question written down.
  • Name the other kind. When why means "I do not want to," you can say so kindly: "That one is not a question, that is a shoes thing. Shoes first, questions after." Warm and clear beats either arguing or caving.

When the questions are hard

Preschoolers ask about death, illness, money and fairness, usually at the least convenient moment. A few things help.

Answer the question they asked, not the one you are afraid of. Children usually want a small, concrete piece of information, not a philosophy. Keep it short, keep it true, and let them come back for more when they are ready. And if you need time, it is completely fine to say "that is an important question and I want to think about how to answer it properly."

What we notice at Shaws

The children who thrive are rarely the ones who arrive knowing the most. They are the ones who keep asking, who will try something they might get wrong, and who are not embarrassed to be puzzled in front of other people.

That is why our teachers answer questions with questions, why our rooms are full of things worth wondering about, and why a walk to look at a spider's web counts as a proper part of the morning. The why phase is not an obstacle to learning. For a while, it is the whole engine.

So on the days when it is relentless, and it will be relentless, it may help to remember what the noise actually is. It is a small person deciding that the world makes sense and that you are the person to ask.

Shaws Preschool has been answering children's questions across the East Coast and Serangoon since 1989, through play-based learning, daily sport and a great deal of time outdoors. Come and see a morning for yourself: book a tour.
