Are behaviors and skills that children reach during typical development. a. stages b. growth markers c. developmental milestones d. observational reports

The correct answer is C) Developmental milestones.

There is usually a predictable course to a child's development, and children will hit certain markers within an age range, such as walking, talking, and identifying letters. Children of course can fall outside of this range, either ahead or behind the curve in this regard. When a child is not reaching these developmental milestones, it can be indicative of a more serious problem.
