By what age should a child be evaluated for potential developmental delays?

A child should be evaluated for potential developmental delays by 18 months because this age marks a critical period for assessing early milestones across various domains, such as speech, motor skills, and social development. At this stage, children are expected to exhibit specific developmental achievements, like saying a few words or displaying social engagement. Early identification of delays can lead to timely interventions, which are crucial in supporting the child's development and improving outcomes.

While evaluations can certainly begin earlier or later, 18 months is often highlighted as a key point for monitoring development, due to the rapid changes that occur during infancy and the need for proactive measures if delays are present. This aligned timing allows for the establishment of baseline developmental skills and provides parents and healthcare providers with the necessary information to support the child effectively.
