What sign may indicate a child aged 18 to 24 months is experiencing developmental issues?

In assessing a child aged 18 to 24 months for developmental milestones, expressive vocabulary is a key indicator of language development. At this age, children typically are expected to have a vocabulary of at least 50 words and be able to combine two words into simple phrases. Using less than 25 words may indicate a delay in language development, which is a significant concern as communication is critical for social and cognitive development.

In contrast, frequently pointing to objects, showing interest in new words, and engaging with peers during play are positive signs of development. Pointing often indicates an understanding of communication and social interaction; interest in new words shows curiosity and a desire to learn; and engagement with peers is a fundamental aspect of developing social skills and relationships. Thus, the number of words a child uses serves as an important benchmark for identifying potential developmental issues.
