Definition:

A developmental regression occurs when a child appears to lose skills they had previously mastered or stops progressing in a specific area of development. This is most commonly noticed in social communication, language, or toileting habits. While it can be a source of significant concern for parents, a regression is a clinical signal that the child’s nervous system or developmental path requires a closer look by a specialist to determine the underlying cause.

• A toddler who used to say "Mama" and "Dada" consistently but suddenly stops using any words at all.
• A child who was successfully potty trained but begins having frequent accidents without a clear medical reason.
• A child who used to wave "bye-bye" or make eye contact but now seems to be "in their own world."

Identifying a regression early is one of the most critical steps in accessing Early Intervention. It allows clinicians to provide immediate support to "re-unlock" those skills and prevent further gaps in development.
