Developmental delays occur when children have not reached developmental milestones by the expected time period.
For example, if the normal range for learning to walk is between 9 and 15 months, and a 20-month-old child has not begun walking, this would be considered a developmental delay. Developmental delays can occur in any or all five areas of development:
- Social and Emotional
- Speech and Language
- Fine Motor Skill
- Gross Motor Skill
Developmental delays may be associated with, but are not limited to, sensory-motor deficits, chromosomal disorders, attention deficits, learning disabilities, pervasive developmental disorder and autism.
