During infancy, the proportions of a baby's head relative to its body are notably different from those in older children and adults. At birth, an infant's head is relatively large, comprising about a quarter of its total body length. This larger head size is essential for brain development, as the brain grows rapidly in the first few years of life, requiring a significant amount of space. As the child grows, the body will develop and lengthen at a faster rate than the head, which makes the head appear proportionally smaller in relation to the body over time.

The term "large" accurately describes the relative size of an infant's head compared to its body during early development stages. In contrast, options like "small," "average," and "proportional" do not accurately reflect the distinctive proportion observed in infants, where the head is noticeably larger than the body.
