Lying and taking things

They told you, with total conviction and chocolate on their face, that they did not eat it. Or they came out of preschool with a toy in their pocket that belongs to someone else.

Both land hard, because both look like early evidence of something about their character. At three, four and five, they are usually about something much more ordinary.

What lying is at this age

For a preschooler the boundary between what happened, what they wish had happened, and what they imagined is genuinely not fixed yet. A great deal of what gets called lying is that boundary being fuzzy rather than a decision to deceive.

There is also plain avoidance: they know you will be cross, and denial is the first tool anyone reaches for. That is not a character flaw, it is a four-year-old with a four-year-old's toolkit.

The useful response is a serious, calm conversation about the difference between make-believe and reality, between lying and telling the truth, and about why honesty matters at home and outside it — rather than a cross-examination. Pushing a small child to confess mostly teaches them that the problem was getting caught.

What taking things is at this age

It is normal for a very young child to take something that catches their interest, and that is not usefully called stealing. It generally is not treated as stealing until a child is old enough — usually somewhere between three and five — to understand that taking something belonging to someone else is wrong.

Once they are old enough to understand it, it is still worth asking what it was for. Children take things to show off to friends, to give as presents so they will be liked, because they do not want to have to ask anyone for anything, or as a way of expressing anger — sometimes with the object standing in for attention or affection they feel short of.

Property rights and consideration for others are taught rather than assumed, and they take repetition.

What actually helps

Make honesty easy to afford. If admitting something always produces a large reaction, denial becomes the rational choice. Naming what you can see — you ate it, and I am not cross that you ate it, I am asking you to tell me the truth — beats setting a trap you already know the answer to.

Put it right rather than punish it. Returning the item, and saying sorry to whoever it belongs to, does far more than a sanction at home.

Notice the honesty when it happens, especially when it cost them something.

Watch what you model. Children are quick to spot the gap between the rule and the household's actual behavior — the pens that came home from the office, the mistake in your favor at the till that got laughed about.

When to ask for help

It is persisting well past the age at which it would usually have settled, and is not shifting with a consistent response.

It comes with other things that worry you — aggression, destructiveness, cruelty to animals, fire-setting, or a marked change in mood.

It looks compulsive, or the child seems unable to explain it or to care about the effect.

There has been a significant change or loss in the family, and this appeared alongside it.

Common questions

Should I make them apologize?
Making them return the item is the more useful half. An apology said under duress teaches less than the experience of handing something back, so do the returning and keep the apology low-key.
They lie even when the truth wouldn't get them in trouble. Why?
Often because the story they are telling is the one they wish were true, which at this age is not the same act as deceiving you. It also becomes habit if denial has worked before.
Is punishing it the wrong approach?
Harsh punishment tends to produce better concealment rather than more honesty. A calm, consistent, unimpressed response combined with putting it right works better at this age.

If it's this, not that

Still not sure

This page is the general answer. Yours is a specific child.

The advisor can be. It has read everything here, and it knows how old your children actually are — which is the whole difference wherever guidance changes with age. Ask it anything.

  • She's got a temperature of 100. Is that something to worry about?
  • He's obsessed with space and galaxies — what toys are worth getting him?

It answers from the same cited pages you are reading, and when the question is where to go, from the real clinician, hospital and childcare records behind this site — not a link to go search them yourself. It says so when we have not written about something, and it is not a doctor; for anything urgent it gives you the threshold and tells you to call.
