Final answer:
Late speech development is an indicator that a child may need evaluation for possible developmental delays, as children are expected to start saying a few words by the end of the first year.
Step-by-step explanation:
An indicator that a child may need evaluation to detect a developmental delay is late speech development. By the end of the first year, a baby typically starts saying a few words.
It is expected that children follow a certain sequence of developmental milestones. Late teething and early crawling are usually not causes for concern as they can vary among children without indicating a developmental issue, and rapid growth is typically expected during certain phases of childhood development.
However, if a child is not reaching language milestones, such as producing words by the expected age, it can be a sign of a potential developmental delay. It is important for caregivers to monitor these milestones and consult with pediatric professionals if they have concerns about their child's development.
