Toddler Behaviour: What Is Normal and What to Expect

One moment your toddler may be affectionate and happily playing beside you. The next, they may be shouting because you cut their toast the wrong way or refusing to put on the shoes they asked for two minutes earlier. If you have wondered whether this behaviour is normal, the reassuring answer is that many dramatic changes in mood, tantrums, frustration, resistance and testing of boundaries are common during the toddler years.

Toddlers are becoming more independent while still developing the language and emotional skills needed to communicate what they want and cope with disappointment. NHS guidance explains that tantrums are very common in toddlers and are often linked to frustration and difficulty expressing feelings.

Normal does not mean easy. Toddler behaviour can be exhausting, particularly when several difficult moments happen in the same day. Understanding what is happening developmentally can make those moments feel a little less mysterious and help you decide when behaviour is simply part of toddlerhood and when it is worth asking for professional advice.

Why toddler behaviour changes so much

Toddlerhood involves a growing desire for independence.

Your child is discovering that they are a separate person with preferences of their own. They may want to choose what they wear, feed themselves, decide which direction to walk or continue playing long after you need to leave.

At the same time, their ability to communicate, wait, compromise and regulate strong emotions is still developing.

That combination can create plenty of conflict.

NHS Best Start in Life explains that toddlers can experience big feelings while struggling to express them. As toddlers become more active and independent, they need adult support to learn how to handle those emotions.

What looks like deliberate misbehaviour may sometimes be a toddler communicating:

“I wanted to do that myself.”
“I don’t know how to tell you what I need.”
“I’m tired.”
“I’m overwhelmed.”
“I don’t want this activity to end.”
“I’m angry that you said no.”

Understanding the reason behind behaviour does not mean removing every boundary. It simply helps you respond to the behaviour with realistic expectations.

Are tantrums normal in toddlers?

Yes. Tantrums are a very common part of toddlerhood.

The NHS says temper tantrums usually start at around 18 months. A toddler may cry, scream, kick, hit or become extremely upset. As children’s language develops and they become better able to communicate, tantrums often become less common.

A tantrum can happen over something that seems very small to an adult.

Perhaps you gave your toddler the wrong cup. Maybe they wanted to press the lift button themselves. Perhaps it is time to leave the playground.

For a toddler, however, the disappointment can feel enormous.

Hunger and tiredness can also contribute to tantrums, according to NHS guidance. Frustration, jealousy and wanting attention may play a part too.

During the most intense part of a tantrum, lengthy explanations are unlikely to be useful. Your first priorities are keeping your child safe and helping the situation become calmer.

Is saying “no” to everything normal?

A determined “no” can become a familiar part of family life during toddlerhood.

Toddlers are beginning to understand that they can make choices and influence what happens around them. Refusing requests can be one way of practising that independence.

This can lead to battles over ordinary things such as:

Getting dressed
Leaving the house
Getting into the pushchair
Washing hands
Tidying toys
Ending an activity
Choosing food

Where appropriate, offering a small choice can give your toddler some control without changing the boundary.

You might ask, “Would you like the red jumper or the blue jumper?”

Both choices still result in getting dressed.

Some situations cannot be negotiated, particularly where safety is involved. You do not need to offer a choice about holding hands near traffic, for example.

Keep essential boundaries simple and predictable.

Hitting, biting and kicking

It can be upsetting when your toddler hits, bites, kicks or pushes, particularly if another child gets hurt.

These behaviours can still occur during normal toddler development.

The NHS says most young children occasionally bite, hit or push another child and that toddlers may not yet understand fully that actions such as biting or pulling hair hurt.

That does not mean the behaviour should be ignored.

Respond calmly and clearly.

You might say, “I won’t let you hit. Hitting hurts.”

If necessary, create space between your toddler and the other person.

Once your child is calmer, you can help them connect the behaviour with the emotion behind it: “You were angry because you wanted the toy.”

This teaches two separate messages. Anger is allowed. Hurting someone is not.

The NHS advises parents not to hit, bite or kick back, because doing so can suggest that this behaviour is acceptable.

Big emotions and sudden mood changes

Toddler emotions can change quickly.

Your child might laugh, cry, become angry and ask for a cuddle within a short period of time.

NHS Best Start in Life explains that toddlers’ brains are still developing and they are only beginning to learn how to manage emotions.

Helping them name feelings can gradually build emotional language.

Simple phrases are enough:

“You look disappointed.”

“You’re angry because we have to go.”

“You’re excited to see Daddy.”

“That frightened you.”

You do not need to solve every emotion.

Sometimes acknowledging the feeling while keeping the boundary is enough.

“I know you wanted another biscuit. You’re disappointed. We’re not having another one now.”

Your toddler may still cry. The fact that they remain upset does not necessarily mean you handled the situation badly.

Clinginess and wanting more attention

Some toddlers go through periods when they want much more contact with a parent or caregiver.

They may become upset when you leave the room, want to be carried more often or repeatedly interrupt when your attention is elsewhere.

Changes can affect children’s behaviour too. NHS guidance lists events such as moving house, having a new baby, changing childminders or starting playgroup among factors that may influence behaviour.

If your toddler suddenly seems more demanding, think about what else may be happening around them.

They might be tired, adjusting to a change or simply seeking reassurance.

Giving positive attention during calm moments can also be helpful. The NHS recommends noticing good behaviour with attention, praise, hugs or smiles rather than allowing difficult behaviour to become the main way a child receives attention.

Testing boundaries

You may feel as though you have told your toddler the same thing hundreds of times.

“Don’t climb on the table.”

“Food stays on the plate.”

“We use gentle hands.”

Toddlers often need boundaries repeated.

They are still learning what happens in different situations and developing the impulse control needed to follow rules consistently.

Try to make important rules straightforward.

If your toddler throws a hard toy, remove it if someone could be hurt and explain briefly why.

If they hit, stop the hitting.

If they refuse to leave somewhere, acknowledge that they are disappointed while continuing with the necessary transition.

Consistency can help children understand what to expect. NHS guidance on child behaviour recommends responding consistently because very different reactions to the same behaviour can be confusing for children.

Consistency does not require perfection. Parents get tired, plans change and family life can be messy. Aim for predictable limits around the things that matter most.

Why toddlers sometimes behave differently with different people

A toddler may behave beautifully at nursery and then have an enormous tantrum shortly after getting home.

Or they may cooperate with one parent while resisting almost everything another parent asks.

Behaviour varies according to context.

Children may be tired after a busy day, responding to different routines or testing different relationships and boundaries.

Instead of treating the contrast as proof that someone is parenting incorrectly, look for patterns.

Ask yourself:

Does the behaviour happen at a particular time?
Is my toddler hungry or tired?
Does it follow a transition?
Is there a particular request that triggers frustration?
Has something recently changed?
Are they struggling to communicate something?

Patterns can give you useful clues without turning every difficult moment into a problem that needs fixing.

What can make toddler behaviour harder?

The NHS lists several common reasons for difficult behaviour in toddlers and young children, including being tired, hungry, overexcited, frustrated or bored.

Changes in family life can also have an effect.

This is why prevention sometimes works better than reacting after behaviour has escalated.

You might notice that your toddler finds long shopping trips difficult when tired, becomes overwhelmed in noisy places or struggles when an enjoyable activity ends suddenly.

Where possible, you can adjust the situation.

A warning before a transition may help: “Two more turns, then we’re going home.”

A snack at the usual time may prevent hunger adding to an already difficult afternoon.

A quieter environment may help an overwhelmed toddler settle.

None of these strategies guarantees perfect behaviour. Toddlers can still have tantrums on well-planned days.

How to respond to difficult toddler behaviour

There is no single parenting technique that works for every toddler or every situation.

A useful starting point is to separate feelings from behaviour.

Your toddler can be angry. They cannot hit.

They can be disappointed. The boundary can still remain.

They can dislike leaving the playground. You can still leave.

NHS Best Start in Life suggests a three-part approach for big emotions: regulate, relate and reason.

First, help your toddler settle. Stay as calm as you can and name what they appear to be feeling.

Then reconnect and offer reassurance.

Only once they are calmer is it useful to explain or reinforce the boundary.

A toddler in the middle of an intense tantrum is unlikely to absorb a complicated lesson. Keep your language short.

Praise the behaviour you want to encourage

Toddler behaviour receives attention very quickly when something goes wrong.

Try to notice what goes well too.

Rather than only saying “good girl” or “good boy”, make praise specific.

“Thank you for putting the blocks away.”

“You waited while I poured your drink.”

“You used gentle hands with the baby.”

The NHS recommends giving children positive attention when they behave well and being specific about what they did.

You do not need to praise every small action throughout the day. Natural acknowledgement is enough.

What is not necessarily a sign that something is wrong?

A single difficult behaviour rarely tells you everything about a child’s development.

Tantrums, occasional hitting or biting, saying no, struggling to share, resisting transitions and becoming frustrated can all occur during toddlerhood.

Children also vary considerably in temperament.

Some toddlers are naturally more cautious. Others are energetic, intense or highly determined. One toddler may have frequent loud tantrums while another becomes quiet and clingy when overwhelmed.

Comparing your child with another toddler can therefore create unnecessary worry.

Look at your child’s overall development and behaviour over time rather than judging them by one difficult afternoon.

When toddler behaviour becomes difficult for the whole family

Something can be developmentally common and still be difficult to live with.

If tantrums, aggression or constant conflict are leaving you exhausted, asking for support is reasonable.

You can start by noting what happens before, during and after difficult behaviour. This may help you identify triggers and can also give a health visitor or GP useful context if you decide to speak to them.

Consider:

What happened immediately beforehand?
What was your toddler trying to do?
Were they tired, hungry or unwell?
How did you respond?
How long did it take for things to settle?
Does the same pattern happen regularly?

You are not trying to build a case against your toddler. You are simply gathering information that may make the behaviour easier to understand.

When to get professional advice

Speak to your health visitor or GP if you are seriously concerned about your toddler’s behaviour, if it is causing significant distress for your child or family, or if you are finding it difficult to cope.

Professional advice is also sensible if behaviour regularly puts your toddler or other people at risk, seems very different from their usual behaviour, or occurs alongside concerns about communication, learning, movement, social interaction or other areas of development.

A significant change in behaviour can sometimes have an underlying reason, so you do not need to assume everything is “just a phase”.

If your toddler loses skills they previously had, seek professional advice rather than waiting to see whether the skills return.

Nursery staff, childminders and other caregivers who know your toddler may also be able to tell you what they observe in other settings.

Most importantly, normal toddler behaviour covers a broad range. Toddlers are learning independence, communication, emotional regulation and social rules at the same time. That learning can look noisy, inconsistent and surprisingly dramatic from the outside.

Your job is not to prevent every tantrum or create perfect behaviour. Calm boundaries, connection and realistic expectations give your toddler space to practise skills that are still developing.
