Most parents notice when something is off with their child. You know your kid. But there’s often a gap between noticing something and knowing what to do about it, or whether it’s serious enough to warrant professional help.
The truth is, children don’t always have the language to tell you what’s happening inside. They show you instead, through their behaviour, their bodies, their moods, their friendships. Knowing what to look for can help you respond early, before things get harder to unwind.
Sign 1: Sudden Changes in Behaviour or Mood
All kids have bad days. Teenagers have bad weeks. That’s not what we’re talking about here.
What warrants attention is a noticeable shift that persists and doesn’t match the circumstances. A child who was generally happy becoming consistently withdrawn or tearful. A previously calm child becoming explosive and reactive. A kid who loved going to school suddenly refusing. A teenager who was open and communicative shutting down completely.
These kinds of changes often signal that something has happened, or is happening, that your child hasn’t been able to process or express directly. It might be a friendship falling apart, a traumatic event, bullying, or the early onset of depression or anxiety.
The duration and intensity matter. A bad week after a hard event is different from two months of sustained change that doesn’t resolve on its own.
Sign 2: Declining School Performance
School is where kids spend most of their waking hours. When something is wrong emotionally, it almost always shows up at school.
Concentration, memory, motivation, all of these are affected by anxiety and depression. A child who is overwhelmed emotionally is not going to be able to bring their full cognitive capacity to learning. Grades dropping, missing assignments, teacher concerns about focus or participation, these aren’t just academic problems. They’re data.
If teachers are reaching out, take it seriously. Teachers see your child in a context you don’t, and they often notice shifts that parents miss because they’re with many children and they can see the baseline.
Sign 3: Social Withdrawal or Increased Aggression
Children communicate distress in two main directions: they pull inward, or they push outward.
Pulling inward looks like dropping friendships, preferring to be alone, losing interest in things they used to enjoy, or becoming quieter and harder to reach. This can be gradual and easy to miss. Parents sometimes attribute it to a phase or the normal self-focus of adolescence.
Pushing outward looks like aggression, defiance, physical fighting, verbal outbursts, or conflict that feels disproportionate and constant. This is often harder to see as distress because it can look like behaviour problems. But a child who is lashing out is frequently a child who is overwhelmed and doesn’t know another way to release it.
Neither response means your child is “troubled” in a permanent sense. Both are calls for help, just in different languages.
Sign 4: Physical Complaints with No Medical Cause
Children’s bodies carry their emotions. Headaches, stomachaches, nausea, and fatigue that keep showing up without a clear medical explanation are worth taking seriously as potential signs of emotional distress.
This isn’t to say the physical symptoms aren’t real. They are. But when a child repeatedly visits the school nurse, misses school due to physical complaints, and a doctor finds nothing wrong, the next question is: what else might be going on?
Anxiety in particular is notorious for this. The body’s stress response is physical. Heart pounding, stomach cramping, muscles tensing. For children who haven’t developed the vocabulary to say “I feel anxious about school,” the body speaks first.
If you’ve ruled out medical causes and the symptoms keep coming, a conversation with a therapist who works with children is a reasonable next step.
Sign 5: Your Gut Is Telling You Something
This one doesn’t fit neatly on a list, but it matters. Parental instinct has real value. If something feels wrong, if you find yourself worried about your child in a way that feels different from ordinary parenting worry, that’s worth paying attention to.
Children don’t need to reach a crisis point before therapy is appropriate. Therapy isn’t only for kids who are seriously struggling. It’s for any child who could benefit from a safe, neutral space to talk about what’s going on with someone who isn’t their parent or teacher.
Some children love having that space. It can be genuinely helpful even when things are going reasonably well, as a place to process the normal difficulty of growing up.
How to Bring It Up with Your Child Without Stigma
This is the part many parents dread. They’re worried their child will feel labeled, embarrassed, or like something is wrong with them.
Be matter-of-fact. The more you treat it like a big deal, the more your child will treat it like a big deal. “I thought it might be helpful to talk to someone whose job is to help kids figure out big feelings” lands differently than a solemn sit-down conversation.
Lead with curiosity, not diagnosis. “I’ve noticed you seem stressed lately and I want to make sure you have support” is better than “I think you have anxiety.” Let the therapist do the assessment.
Normalize it. Lots of kids see therapists. Lots of adults do. Framing it as a normal resource rather than a last resort changes the conversation. And if your child is reluctant, that’s okay. You can acknowledge it while still moving forward. You don’t need your child’s enthusiasm to book the first appointment.
At InnerSight Psychotherapy in Vaughan, our therapists who work with children and teens create an environment that feels low-pressure and non-clinical. The goal is for your child to feel heard, not evaluated. If you’re not sure whether your child needs support, a consultation call can help you get a clearer sense.
