Which of the following may suggest that a child is not following typical developmental milestones?

The inability to form letters can indicate that a child may not be following typical developmental milestones. As children grow, they are expected to develop fine motor skills, which include the ability to grasp, manipulate objects, and eventually write or form letters. Typically, by the age of five or six, children should start showing progress in writing letters and numbers as part of their educational development. If a child struggles significantly with this skill, it may suggest delays in both fine motor development and cognitive skills related to writing.

In contrast, playing with peers generally aligns with social development milestones, finding words that rhyme demonstrates phonemic awareness vital for literacy development, and having a regular sleep schedule is often associated with healthy routine behaviors rather than developmental concerns. Thus, while the other options reflect typical skills or behaviors that suggest a child is developing normally, the inability to form letters stands out as a potential indicator of developmental delay.
