Update : October 16, 2025


Getting a diagnosis of developmental language disorder (DLD) can take time, but it opens the doors to valuable resources that will support your child’s development. This article breaks down how to recognize signs of DLD, the role of professionals, and the key steps to obtaining a diagnosis for your child.

Early Signs

Have you noticed that your child is often at a loss for words or has difficulty making themself understood? As a parent, it’s normal to ask yourself questions and try to understand what’s going on.

Here are a few signs that may indicate language difficulties in a young child. Note that these signs are not specific to DLD.

Signs to watch for depending on the age,

Note that these signs are just indicators. Signs and symptoms may vary from child to child. Your child does not need to display every one of these indicators in order to see a specialist. 

Did you know
  • Only one in two children with a DLD is identified before the age of 5.[1]
  • A child who speaks their first words after the age of 2 is 6 times more likely to live with DLD.[2]

The Diagnostic Process

If you have concerns, it’s important to act early. Here are a few steps you can take to get an assessment.

  • Contact your local CISSS for an assessment.  
  • Find a private clinic on the Ordre des orthophonistes et audiologistes du Québec website.
  • Have your child’s hearing checked by a doctor or audiologist, as frequent ear infections or congestion can have an impact on language development.

The only professionals who can diagnose DLD are speech therapists and neuropsychologists. However, other professionals from the public, private, or community sectors can help you support your child.

  • Resource teacher: A teacher specialized in learning difficulties in the areas of reading, writing, and mathematics.
  • Psychologist: An expert in behaviour, emotions, and mental health. Psychologists work with people with psychological struggles.
  • Social worker: Helps individuals and families experiencing struggles and crises.
  • Occupational therapist: A professional who helps people organize and carry out daily life activities.
  • Psychoeducator: Works with people who have adjustment difficulties that have behavioural impacts in various settings.
  • Special education technician: A professional who works with people of all ages experiencing a variety of adjustment difficulties in different settings.
  • Audiologist: A professional who prevents, assesses, and treats hearing problems.

A diagnosis is not a label to be attached to a child, but rather a key to understanding the difficulties they encounter and opening doors to concrete support.
A diagnosis can help you access many resources, such as rehabilitation services, support and accommodations at school, an individualized education plan, and adaptive measures in the classroom. A diagnosis may even qualify you for subsidies offered under certain government programs.

Tips and tools

Even if you’re still waiting for an assessment or a consultation with a specialist, you can take concrete steps to help your child.

  • Write down your daily observations.
  • Limit screen time to encourage real-life interactions.
  • Stimulate your child’s language by talking, playing, and reading with them.
  • If possible, consult a language stimulation specialist.
  • Contact community organizations in your area that can help you.
