Which statement is true about developmental stages?

Developmental stages are indeed influenced by a variety of factors, which means they can fluctuate over time. This variability can be attributed to numerous influences, including genetics, environment, cultural practices, and individual experiences. Children might reach developmental milestones at different times due to differences in these influencing factors. For example, while some children may speak their first words by age one, others may achieve this milestone a bit later, and that's perfectly normal.

The concept of developmental stages recognizes that growth is not a one-size-fits-all process. It is dynamic and can change based on personal circumstances, health, socioeconomic status, and support systems surrounding the child. This understanding is critical for those working with children, as it underscores the importance of personalized approaches in nurturing development.

In contrast, the other statements present a more rigid understanding of development that doesn't align with current research and observations in child psychology and child development. Development is recognized as a fluid process, highlighting the need for flexibility in expectations and strategies when it comes to supporting children as they grow.
