What does it mean that developmental sequences are similar for all children?

The statement that developmental sequences are similar for all children refers to the consistent patterns observed in the order of developmental milestones, despite variations in the timing of these milestones among different children. The correct choice indicates that most children crawl before they walk, which highlights a universal aspect of motor development. This sequence—crawling followed by walking—is a common pathway in early physical development, emphasizing that while individual children may reach these milestones at different ages, the order of progression tends to remain constant.

This principle reflects the idea that certain developmental tasks serve as foundational skills that prepare children for subsequent abilities. For instance, crawling not only helps to develop muscle strength and coordination but also facilitates spatial awareness, which is crucial for walking. The recognition of this pattern underscores the predictable nature of child development across a diverse population, summarizing how similar biological and neurological processes guide children through their early growth stages.
