Language Development

Language development starts at birth and continues for the rest of our lives. 

Below is a checklist of language skills from birth to 5 years of age. It touches on what a child should be able to understand and say by a certain age.

Of course, all children are different and this is just a guideline. If you are concerned about your child, please contact a speech-language pathologist for an evaluation.
