Developmental milestones are one way of seeing if your child’s development matches that of typically developing peers.
If your child is not showing the following speech, language, and related skills, a consultation is recommended with a licensed speech-language pathologist who can provide you with suggestions which may prevent a communication problem from developing and determine if a screening test or in-depth diagnostic testing is needed.
Please refer to our Glossary of Terms for an explanation of the terms used throughout the milestone checklists.
