Developmentally Appropriate Behavior in Children: What’s Normal and When to Seek Help

"My child whines about everything."

"My toddler has a meltdown when I say no."

"My 6-year-old cries when they lose."

"My 10-year-old argues with everything I say."

"My teenager suddenly wants nothing to do with me."

As therapists, we hear concerns like these all the time. And very often, parents are asking the same underlying question:

Is this normal?

The answer is often yes.

Children are not miniature adults. Their brains, communication skills, emotional regulation, impulse control, and ability to understand other people's perspectives are still developing. Behaviors that would be concerning or inappropriate for an adult can be completely developmentally appropriate for a child.

That doesn't mean parents have to allow every behavior. It means we need to understand why the behavior is happening before deciding how to respond to it.

Developmentally Appropriate Behavior Does Not Mean "Anything Goes"

One of the most important distinctions for parents to understand is this:

A behavior can be developmentally normal and still need correction.

A toddler hitting when angry may be developmentally understandable. We still don't allow hitting.

A preschooler having a tantrum because they didn't get what they wanted may be developmentally expected. We still don't have to change our answer.

A school-age child whining because they don't want to clean their room may be normal. We can still expect them to complete the task.

Understanding development changes how we respond. Instead of viewing the child as manipulative, disrespectful, bad, or intentionally difficult, we can recognize that the child may not yet have the skills necessary to manage the situation differently.

Our job then becomes teaching those skills.

Toddlers: Approximately Ages 1 to 3

Toddlerhood can be an exhausting stage for parents. Children are developing independence much faster than they are developing self-control.

Common behaviors during this stage can include:

• Tantrums

• Whining and crying

• Saying "no"

• Hitting, biting, kicking, or throwing

• Difficulty sharing

• Grabbing toys

• Difficulty waiting

• Separation anxiety

• Rapid changes in emotions

• Becoming extremely upset over seemingly small things

• Wanting to do something independently and then becoming frustrated when they cannot

• Resistance to transitions, bedtime, getting dressed, or leaving preferred activities

A toddler may desperately want independence while still needing significant help from adults.

Imagine wanting to communicate something important but not having the vocabulary to explain it. Then imagine being told "no" without having the emotional regulation necessary to tolerate disappointment.

That is toddlerhood.

What Parents Can Do

Keep expectations simple and consistent. Use short instructions, offer limited choices when possible, redirect inappropriate behavior, and maintain boundaries without expecting a toddler to respond with adult-level emotional control.

For example:

"I won't let you hit. You're angry. You can stomp your feet or tell me you're mad."

The goal isn't to prevent the child from ever becoming angry. The goal is to gradually teach them what to do with anger.

Preschoolers: Approximately Ages 3 to 5

Preschoolers usually have more language than toddlers, but their emotional regulation and impulse control are still developing.

Parents may see:

• Whining

• Tantrums, particularly when tired, hungry, overstimulated, or frustrated

• Difficulty losing games

• Interrupting

• Trouble sharing or taking turns

• Boundary testing

• Arguing

• Bossiness

• Jealousy

• Difficulty transitioning away from preferred activities

• Big reactions to small disappointments

• Imaginative stories that aren't entirely factual

• Wanting to do everything independently

• Repetitive questions

This is also an age when imagination is incredibly active. Young children do not always understand truth, fantasy, exaggeration, and deception in the same way adults do. A preschooler telling an inaccurate story does not automatically mean the child is intentionally "lying."

What Parents Can Do

Focus on teaching the behavior you want to see rather than simply punishing the behavior you don't want.

Instead of:

"Stop whining."

Try:

"I want to hear you. Try asking me in your regular voice."

Instead of:

"You're being ridiculous. There's nothing to cry about."

Try:

"You're disappointed. It's okay to be disappointed. The answer is still no."

Validation does not mean giving in.

You can acknowledge a child's feelings while maintaining the exact same boundary.

Early Elementary Years: Approximately Ages 5 to 7

Children entering school are developing more self-control, but they are still learning how to navigate friendships, competition, rules, expectations, and increasingly complex emotions.

Common behaviors can include:

• Complaining

• Whining when tired or overwhelmed

• Tattling

• Being highly concerned with fairness

• Difficulty losing

• Comparing themselves with peers

• Emotional outbursts

• Wanting adult approval

• Becoming upset when corrected

• Sibling jealousy

• Difficulty seeing another person's perspective

• Testing rules and boundaries

Parents sometimes expect a dramatic increase in emotional maturity once a child starts school. Development doesn't happen that quickly.

A 6-year-old may understand a rule perfectly and still struggle to follow it when angry, tired, embarrassed, disappointed, or overstimulated.

Knowing a skill and being able to use that skill while emotionally overwhelmed are two different things.

Middle Childhood: Approximately Ages 7 to 10

During middle childhood, peer relationships and social comparison become increasingly important.

Parents may notice:

• Increased arguing or negotiation

• Complaints about fairness

• Sensitivity to criticism

• Embarrassment

• Comparing themselves to siblings or peers

• Wanting more independence

• Strong reactions to friendship problems

• Increased awareness of social acceptance

• Testing parental rules

• Wanting more privacy

• Becoming frustrated when parents "don't understand"

At this age, children are developing more sophisticated reasoning abilities. Unfortunately for parents, that means they may also become much better at arguing their position.

Arguing does not necessarily mean a child is disrespectful. Sometimes it reflects growing independence, reasoning skills, and a desire to have some control over their environment.

Parents can acknowledge the child's perspective without turning every boundary into a negotiation.

For Example:

"I understand that you disagree with me. You are allowed to disagree. The expectation is still the same."

Tweens: Approximately Ages 10 to 12

The transition toward adolescence can bring significant changes.

Children may become:

• More private

• More self-conscious

• More influenced by peers

• Sensitive to criticism

• Concerned about appearance and belonging

• More likely to question family rules

• More emotionally reactive

• Less interested in sharing everything with parents

• More interested in making their own decisions

Parents sometimes interpret this growing independence as rejection.

In many cases, however, a child pulling away slightly is doing exactly what development requires: beginning the gradual process of developing an identity separate from their parents.

They still need connection, boundaries, supervision, and reassurance. They may simply need those things delivered differently than they did when they were 7.

Adolescence

Teenagers are moving toward adulthood, but their brains are still developing.

Adolescence commonly involves:

• Increased desire for independence

• Greater need for privacy

• Questioning parental rules and beliefs

• Strong peer influence

• Emotional intensity

• Identity exploration

• Increased risk-taking

• Conflict with parents

• Sensitivity to criticism or rejection

• Wanting greater control over schedules, friendships, clothing, activities, and decisions

Conflict between teenagers and parents does not automatically mean the relationship is unhealthy.

Some conflict is expected when one person is saying, "I am becoming independent," while another is responsible for saying, "You aren't completely independent yet."

The goal isn't necessarily to eliminate disagreement. The goal is to create a relationship in which disagreement can occur while maintaining safety, respect, connection, and appropriate parental boundaries.

What About Whining?

Whining deserves its own discussion because almost every parent finds it irritating.

Whining can serve several purposes. A child may be tired, hungry, overwhelmed, seeking attention, frustrated, or simply using a communication strategy that has worked before.

Parents do not have to reward whining.

However, repeatedly saying "STOP WHINING!" doesn't necessarily teach the child what to do instead.

Try teaching the replacement behavior:

"I can tell you need something. Ask me in your regular voice."

When the child does:

"Thank you for asking me that way."

Notice what happened. The parent didn't give in to the request. The parent taught a communication skill.

What About Tantrums?

Tantrums are particularly common in toddlerhood and the preschool years because children experience intense emotions before they have fully developed the ability to regulate them.

During a tantrum, parents often start explaining:

"You can't have another cookie because you already had one, and we're eating dinner in 30 minutes, and you know we don't eat treats before dinner..."

Your screaming 3-year-old probably isn't processing that lecture.

When children are highly dysregulated, keep language simple.

"You're really mad. I won't let you hit."

Then maintain the boundary.

The teaching conversation can happen once the child is calm.

Behavior Is Communication, But It Still Requires Boundaries

You may have heard the phrase "behavior is communication."

That's true, but sometimes it gets misunderstood.

Understanding why a behavior is happening does not mean allowing the behavior.

If a child hits because they are overwhelmed, we address the overwhelm and stop the hitting.

If a child screams because they are disappointed, we help them tolerate disappointment without changing the boundary simply to stop the screaming.

If a child avoids something because they are anxious, we acknowledge the anxiety while helping them gradually develop the ability to face difficult situations.

We can be compassionate and maintain expectations at the same time.

Ask a Different Question

When challenging behavior happens, our first thought is often:

"How do I make my child stop doing this?"

Try asking:

"What skill would my child need in order to handle this differently?"

Maybe the missing skill is:

• Emotional regulation

• Communication

• Frustration tolerance

• Impulse control

• Flexibility

• Problem-solving

• Perspective-taking

• Conflict resolution

• Identifying emotions

• Asking for help

• Tolerating disappointment

Once we identify the missing skill, discipline becomes much more effective because we can actually teach something.

Does My Child Need Therapy, or Is This Something We Can Handle at Home?

Not every difficult behavior requires therapy.

In fact, many of the behaviors that frustrate parents the most are a normal part of development. Whining, tantrums, arguing, difficulty sharing, testing limits, complaining, refusing, becoming upset when told no, and struggling with disappointment can all occur in typically developing children.

Sometimes the child doesn't need therapy. Sometimes the child needs parents who understand the developmental stage, respond consistently, set appropriate boundaries, and teach the skills that are still developing.

Therapy should not be used simply to make normal childhood behavior disappear.

Sometimes the Parent Needs Support More Than the Child Needs Therapy

There is another possibility that is important to talk about.

Sometimes a family needs professional support, but individual therapy for the child isn't necessarily the most appropriate intervention.

Parents may benefit from parent coaching or family-based support.

A therapist cannot be expected to "fix" a child's behavior during one hour of therapy each week if the behavior is being shaped by what happens during the other hours of the child's life.

Parents and caregivers are one of the most important parts of behavior change.

For younger children especially, effective treatment may involve significant parent participation rather than simply sending the child into a therapy room alone.

When Might the Child Need Therapy?

Therapy becomes more appropriate when the issue appears to extend beyond ordinary developmental challenges.

Rather than focusing on one specific behavior, we look at frequency, intensity, duration, developmental appropriateness, safety, distress, and impairment.

Consider seeking an evaluation when:

• The behavior is significantly more intense or frequent than would typically be expected for the child's developmental level.

• Emotional or behavioral difficulties are interfering with school, friendships, family relationships, sleep, activities, or everyday functioning.

• The child seems unable to recover from emotional distress even with appropriate adult support.

• Anxiety, sadness, anger, fear, or irritability is persistent and causing significant distress.

• The child is consistently avoiding developmentally appropriate activities because of anxiety or fear.

• Aggression is severe, frequent, or creating safety concerns.

• The child is harming themselves, talking about harming themselves, or expressing thoughts of suicide.

• There has been a significant change from the child's previous functioning.

• The child has experienced trauma, loss, family disruption, abuse, or another significant stressor and appears to be struggling to cope.

• Behaviors continue or worsen despite consistent, developmentally appropriate parenting strategies.

• Difficulties occur across multiple environments rather than only in one very specific situation.

• Parents, teachers, pediatricians, or other caregivers consistently notice that the child's functioning seems substantially different from that of similarly aged children.

• 
  

The question is not simply:

"Does my child have tantrums?"

A more useful set of questions is:

How often? How intense are they? How long do they last? What triggers them? Can the child recover? Are they getting better as the child develops? Are they interfering with the child's ability to function?

Context matters.

What About Neurodivergent Children?

Development does not look exactly the same for every child. Children with ADHD, autism, learning differences, sensory processing differences, or other forms of neurodivergence may develop certain skills on a different timeline or experience everyday situations differently than their peers.

For example, a neurodivergent child may have more difficulty with transitions, impulse control, emotional regulation, flexibility, sensory overload, social expectations, or communicating what they need. What looks like "defiance," ignoring, overreacting, or refusing may sometimes reflect an overwhelmed nervous system, difficulty shifting attention, sensory discomfort, or a skill the child has not yet developed.

This does not mean neurodivergent children do not need boundaries or expectations. Rather, expectations and parenting strategies may need to be adjusted to the individual child's developmental abilities and needs.

When evaluating behavior, it is important to ask not only, "Is this typical for a child this age?" but also, "Is this reasonable given this particular child's developmental profile?"

If a child's differences are consistently interfering with learning, relationships, daily functioning, or their ability to participate in age-appropriate activities, an evaluation may help parents better understand what is happening. The goal is not simply to stop the behavior. It is to understand the child well enough to provide the right support.

Therapy Isn't a Consequence for Misbehavior

It is also important that children don't receive the message that therapy is where they are sent because they are "bad."

Statements such as:

"If you keep acting like this, I'm taking you back to your therapist."

or

"You need therapy because you don't listen."

can unintentionally turn therapy into a punishment.

Therapy is a resource for children and families when additional support is needed. It can help children develop skills, understand their emotions, process difficult experiences, improve relationships, and address mental health concerns.

But children are also allowed to have difficult moments without every difficult moment becoming a mental health problem.

Beehive Family Services provides therapy and support for children, teens, parents, and families. If you're concerned about your child's behavior, emotional development, or family relationships, our clinicians can help you better understand what may be happening and determine whether additional support would be beneficial.

Additionally, if you want to learn parenting skills specific to neurodivergent children, one of our therapists, Hunter Jones, provides parent coaching services.
