Which language behavior in a four-year-old child would likely signal the need for intervention and monitoring?

A four-year-old child who uses gestures and unintelligible words may indicate a significant communication delay or issue, warranting intervention and monitoring. At this age, children are typically expected to communicate using clear, recognizable words and simple sentences. If a child primarily relies on gestures and lacks clarity in their speech, it may suggest difficulties in language development, which could affect their ability to engage with peers and participate in educational settings.

Monitoring and possible intervention would help ensure that the child receives the support they need to develop their communication skills appropriately. This could include speech therapy or other resources to help the child develop clearer speech and vocabulary usage, enabling them to express their needs and thoughts more effectively as they grow.
