What is a common symptom of developmental delay in young children?

A common symptom of developmental delay in young children is difficulty in speech or language development. This symptom often manifests as late or unclear speech, challenges in understanding language, or struggles with expressing thoughts and ideas effectively. Language development is critical in early childhood, as it impacts communication skills and social interactions. When children exhibit delays in this area, it is often an indicator that they may require additional support to develop their language abilities, which are integral for their overall developmental progress.

In contrast, diminished physical growth can indicate various health issues but is not specific to developmental delays. Excessive aggression towards peers typically reflects behavioral or social-emotional concerns rather than developmental delays. Advanced problem-solving skills are generally associated with above-average cognitive development and are not indicative of developmental delays. Thus, difficulty in speech or language development aligns closely with recognized symptoms of developmental delay, making it the correct choice.
