Another evening ends in an argument over brushing teeth. Your son has been waking up crying almost every night for weeks. Your daughter, once outgoing and talkative, now spends more and more time alone in her room.

At some point, many parents find themselves asking the same question we hear almost every day in our clinic:

Is this just a developmental phase my child will grow out of, or is it a sign that deserves closer attention?

The answer is rarely straightforward.

Child development does not follow a straight line. Emotional ups and downs, increased sensitivity, oppositional behaviour or temporary regressions can all be part of healthy development. At the same time, some behavioural changes may signal emotional or developmental difficulties that warrant professional assessment.

Development comes in waves, not in a straight line

According to Arnold Gesell's Maturational Theory, children's development progresses through alternating periods of balance and imbalance.

After a stage in which a child is calm, cooperative and emotionally regulated, it is perfectly normal for a more challenging period to emerge. Children may become more oppositional, emotionally reactive or difficult to cooperate with.

Gesell argued that these temporary periods of disequilibrium are a necessary part of healthy development. Before reaching a new level of maturity, children often go through a phase in which previously stable behaviours appear to "fall apart."

Rather than progressing in a straight line, development unfolds in cycles of stability and transition.

For parents, this is often reassuring: a temporary deterioration in behaviour does not automatically mean that something is wrong with their child—or that they are doing something wrong.

However, there is an important distinction.

Developmental challenges are typically temporary, age-appropriate, and gradually improve over time. When behavioural changes become persistent, intensify, or begin to interfere with everyday functioning, they deserve a closer look.

Contemporary developmental psychology continues to support this perspective. Temporary behavioural changes often accompany periods of rapid cognitive, emotional or social development and, by themselves, do not indicate a mental health disorder.

Four questions that can help

Before looking at specific warning signs, clinicians often consider four key questions:

• How long has it been going on? Developmental phases usually resolve within a few weeks.

• Is it getting better or worse? Healthy developmental challenges gradually become less intense rather than escalating.

• Does it happen everywhere or only in one setting? Behaviour that occurs both at home and at school carries different clinical significance than behaviour limited to one environment.

• Is this typical for your child? A sudden and marked change from your child's usual behaviour deserves more attention than long-standing temperament traits.

These questions provide an important framework for deciding whether a child may benefit from further assessment.

12 Signs Worth Paying Attention To

Duration and Pattern

The behaviour persists for more than a few weeks.Despite support at home, conversations, and changes in parenting strategies, there is little or no improvement.

The difficulties become more pronounced over time.Rather than gradually settling, episodes become more frequent, last longer, or increase in intensity from week to week.

Intensity and Emotional Regulation

The child's reactions are disproportionate to the situation.A seemingly minor event—such as a change of plans, being told "no," or a small frustration—triggers an emotional response that appears far greater than the situation would normally warrant.

Your child struggles to calm down.Even long after the upsetting event has passed, they remain distressed, and the usual calming strategies no longer seem effective.

The behaviour occurs without an obvious trigger.Emotional outbursts or withdrawal happen suddenly, without a clear cause, making them difficult for both the child and the parent to anticipate.

Research shows that self-regulation develops gradually throughout childhood. Younger children naturally rely on adults to help them regulate their emotions, but as they grow older, they should generally recover emotional balance more quickly.

Impact on Everyday Functioning

The difficulties occur in more than one setting.The same pattern of behaviour is observed not only at home, but also at nursery, school, or in interactions with peers.

The behaviour affects relationships with others. Your child begins losing friendships, is avoided by peers, or withdraws from social activities they previously enjoyed.

Family life becomes significantly disrupted. Daily routines—such as meals, bedtime, or leaving the house—regularly become sources of conflict, tension, or emotional crises.

A Noticeable Change from Your Child's Usual Behaviour

Your child loses previously acquired skills. You notice regression in speech, independence, toileting, or other developmental areas in which they had already become more confident.

The change is sudden and clearly differs from your child's usual temperament.A child who was once calm, outgoing, or confident suddenly becomes someone you barely recognise.

Signs That Require Prompt Professional Assessment

Physical symptoms appear without a medical explanation. Recurring stomach aches, headaches, nausea, or other physical complaints consistently occur in specific situations—such as before school—despite normal medical examinations.

Your child talks about sadness, anxiety, hopelessness, withdraws emotionally, or shows signs of self-harming behaviour.These warning signs should never be ignored and require prompt assessment by an appropriate healthcare professional.

According to the World Health Organization (WHO), around 13% of children and adolescents worldwide experience a mental health condition, yet many do not receive professional support until months after the first symptoms appear.

If you recognise several of these signs in your child, the first step is to speak with a qualified professional who can help determine whether you are observing a normal developmental phase or a difficulty that requires further assessment.

At Równoważni MED, psychological consultations are provided by clinicians experienced in assessing ADHD, autism spectrum conditions, and emotional and behavioural difficulties.

What Can Parents Do Before Booking an Appointment? Before your child is assessed, it can be helpful to record a few observations that will support the diagnostic process:

• When did the behaviour first become more noticeable?

• In which situations does it occur most often?

• What usually happens immediately beforehand?

• How long does it take for your child to calm down afterwards?

It is also worth asking teachers or other adults who spend time with your child whether they have noticed similar patterns. Consistent observations across different environments provide valuable diagnostic information.

At the same time, approaching your child's behaviour with patience and curiosity remains important—regardless of whether it ultimately proves to be a temporary developmental phase or an indication that further assessment is needed.

Blaming your child—or yourself—rarely helps. Careful observation, compassion, and seeking professional advice when in doubt are far more constructive.

Q&A

Child development is not a race along the shortest or easiest path. It is a natural journey, marked by periods of growth, stability, and challenge that unfold over time. Understanding the difference between a typical developmental phase and signs that may require professional attention is not about replacing expert assessment—it is about helping parents make informed decisions with greater confidence and less self-blame.

You do not have to figure it out on your own.

If you are wondering whether your child's behaviour is simply part of development or a sign that deserves closer attention, consider booking a psychological consultation at Równoważni MED. Our specialists are here to help you understand what your child may be experiencing and, if needed, guide you towards the most appropriate support.
