Beyond the Behavior — Column 02

Every child has hard days. A preschooler falls apart at pickup. A fifth grader snaps at a younger brother. A teenager rolls their eyes and closes the bedroom door a little too hard. These moments are exhausting, but they are part of growing up.

There is a difference, though, between a hard day and a change. When a child who has been doing reasonably well begins to act differently—consistently, over days or weeks—that shift is one of the most reliable early signals that something in the child’s world needs attention.

Why the change matters more than the incident

Adults naturally react to the moment in front of them: the outburst in the grocery store, the fight at recess, the assignment that never got started. But a single incident rarely tells us much on its own. What tells us more is the shift away from what is typical for this particular child.

Consider what that shift can look like:

A social child who stops wanting to play with friends and starts sitting alone at lunch.
A calm child who begins hitting, throwing things, or using language that feels out of character.
A steady student who suddenly says “I don’t care” and stops turning in work.
A toilet-trained child who begins having accidents, or a child who starts having nightmares and resisting bedtime.
A teenager who quits the team, stops answering friends’ texts, and spends most of the day asleep or alone.

None of these, by themselves, confirms a diagnosis or a crisis. Each one is a departure from what is usual for that child. That departure is what we pay attention to.

The explanations we reach for

When behavior changes, adults tend to grab a familiar explanation: it’s a phase, they want attention, they’re testing limits, it’s just hormones, they need more discipline. Sometimes those explanations are partly right. But when we stop there, we can miss what the child actually needs.

One assumption deserves special caution: “They’re fine because they were fine before.” Past success does not protect a child from present struggle. A child can be resilient and still be hurting. A child can look fine on the surface and be overwhelmed underneath.

What may actually be happening

In Tantrum, Meltdown, or Something More?, I describe several broad possibilities adults can keep in mind:

Something happened. An event the child has not mentioned—a conflict with a friend, bullying, a loss, a frightening experience. Children often don’t tell adults directly, especially when they feel ashamed or unsure they will be believed.
Something is building. Stress accumulates. A child may handle one stressor and come undone when a second or third is added.
Something is developing. Learning differences and mental health concerns often emerge gradually and become visible when demands increase. [1]
Something in the environment shifted. A new teacher, a move, a new baby, a parent’s new work schedule, an illness in the family.
Something physical changed. Poor sleep, pain, hunger, illness, puberty, or a medication side effect can look emotional or behavioral.

What to do first

You do not need all the answers when you first notice a change. Three steps are enough to begin.

Observe without labeling. Instead of “He’s being defiant,” try “He’s been putting his head down when independent work starts.” Neutral descriptions keep more explanations on the table.

Stay connected. Children who are struggling sometimes push adults away. That is exactly when connection matters most. You do not have to approve of a behavior to stay warm toward the child: “I’m noticing things seem different for you lately. I’m here whenever you’re ready.”

Write it down. Keep a simple log—the date, what you saw, where, who was there, what happened right before, and how the child seemed afterward. You are not building a case against the child. You are collecting information that may help later, whether in a conversation with a teacher, a pediatrician, or a school team.

How to talk with the child

Choose a calm, private moment—not right after an incident and not in front of siblings or classmates. Lead with what you noticed rather than an accusation: “I’ve noticed you haven’t wanted to go to practice lately. That’s different for you.” Let the child know they are not in trouble. If they are not ready to talk, accept that and leave the door open. Some children need several invitations before they feel safe enough to share.

If a child does tell you something, resist the urge to minimize it, question it, or fix it right away. Listen. Thank them for telling you. Then decide on next steps together.

When to seek more support

Reach out to the child’s school, pediatrician, or a mental health professional when a change lasts more than about two weeks without improvement, significantly affects daily life, or puts anyone at risk. If a child talks about wanting to hurt themselves or not wanting to be alive, act right away: call or text 988, or call 911 in an emergency. [2]

And trust your instinct. You know this child. If something feels off, it is worth a closer look.

A message worth carrying forward

Behavior change is a signal. It is not always a crisis, but it always deserves attention. The sooner adults notice a shift, describe it without judgment, and share what they see across home and school, the sooner a child can get the support they need.
