Milestones in development are achieved in a fixed timetable for all children. True or false?

• A. True
• B. False
• C. Usually, but with exceptions
• D. Only in certain cultures

Answer: (B)

Development milestones occur along a range, not a fixed timetable. While there are typical ages when children commonly reach certain skills, individual children vary widely in when they achieve them. This variation comes from genetics, health, nutrition, opportunities to practice skills, and environmental factors. For example, many babies begin to sit without support within a broad window, start walking around a general range, and say their first words at different times. A child outside the typical range isn’t automatically “behind” and may just be developing at their own pace, though ongoing concerns can warrant screening. So the statement is not accurate because development is diverse, not the same timetable for everyone.
