Developmental Milestones

Milestones are what 90% of children are doing at that age.

The average is what 50% or children are doing at that age.

Every child grows and develops at their own pace. Developmental milestones provide us with a guide of when most children have developed a specific skill. It may not be a cause for concern if your child is not meeting a milestone listed. However, if your child is not meeting many of the milestones listed below, it would be best to get in touch with a licensed speech-language pathologist. 
Having a communication disorder, whether it is speech or language based, can affect the way we connect with others and the world around us. It can also cause social, emotional, and behavioural problems if not addressed. If you have any questions or concerns at all, give us a call today.
Early intervention is key.
