Understanding Autism Spectrum Disorder (ASD): A Guide for Parents

Whether your child is a toddler or a teenager, noticing that they experience the world a little differently than their peers can bring up a lot of questions and a lot of feelings. You might be watching your two-year-old and wondering why they don’t respond to their name, or you might be the parent of a teen who’s always felt a step out of sync socially and are only now hearing the word “autism” said out loud. Both are valid starting points, and both deserve real answers.

Autism Spectrum Disorder (ASD) affects every child differently, that’s the nature of a spectrum. Some children show clear signs in infancy; others aren’t recognized until adolescence or even adulthood, especially those with what’s sometimes called “higher functioning” autism. There’s no single way ASD looks, which is exactly why noticing your own child’s patterns, rather than comparing to a checklist alone, matters so much.

Common Signs to Watch For

ASD symptoms typically emerge early in development, though how they show up — and when they become noticeable — varies widely from child to child. Common signs include:

• Avoiding eye contact or showing limited facial expression
• Little interest in other people, or in sharing experiences with other children
• Not responding, or responding minimally, to their own name
• Repetitive behaviours, or an intense focus on specific interests
• Difficulty understanding how others are feeling
• Delayed speech development
• Trouble communicating wants and needs
• Difficulty coping with changes to routines or plans
• Unusual responses to sensory input — from their own body, other people, or their surroundings
• Difficulty building or keeping age-appropriate friendships

For younger children, these signs are often noticed at home first, in play, in routines, in how they connect (or don’t) with siblings and other kids. For teens, ASD can look less like the “textbook” signs and more like social exhaustion, a small tight circle of intense interests, difficulty reading unspoken social rules, or a lifetime of feeling like they’re working harder than their peers just to keep up.

When Signs Typically Appear

Red flags can sometimes be noticed before age one, and symptoms often become clearer between ages two and four. But autism doesn’t always announce itself early. Many kids, especially those with milder or masked presentations, aren’t identified until later childhood or the teen years. Whenever it happens, an evaluation is a valuable next step. Working with your family doctor, a psychologist and therapists to understand your child’s specific needs, whether at 3 or at 17, makes a real difference in the support they receive.

Support That Helps

The exact cause of ASD isn’t fully understood, but a great deal is understood about what helps. At Canoe, we recommend early intervention approaches such as behaviour therapy and speech-language therapy, which help children build social understanding and communicate more comfortably, alongside occupational therapy, which supports play skills, self-help skills, fine motor development, and sensory needs. For teens, therapy often shifts to focus on social skills, self-advocacy, and building confidence in their own way of navigating the world.

We also offer a variety of camps and groups throughout the year, along with regular therapy sessions to help kids of all ages build the skills that matter most to them.
