Which observation indicates a deficit that might require further evaluation for speech development?

Using simplified phrases and "baby talk" indicates a potential deficit in speech development because it suggests that the child may not be developing language skills in a way that is age-appropriate. Children are typically expected to progress from simple speech patterns to more complex and varied forms of communication as they grow. Consistently using simplified phrases or regressing to "baby talk" might point to a lack of growth in vocabulary, pronunciation, or comprehension skills.

In contrast, successfully using direct questions and consistently speaking in complete sentences reflect a healthy development of language skills. Engaging with technology during lessons, while an important aspect of modern learning, does not directly inform us about a child's speech and language capabilities. Therefore, the observation of relying on simplified speech forms can serve as a red flag that might warrant further assessment to ensure the child is receiving appropriate support for their speech development.
