How does a babys physical proportions compare with those of an adult?

Babies have distinct physical proportions compared to adults; their heads are relatively larger in proportion to their bodies, making up about 25% of their total length, while an adult's head accounts for about 12-15%. Additionally, infants have shorter legs and a higher body fat percentage, which gives them a rounder appearance. As they grow, their body proportions gradually shift to resemble those of adults, with longer legs and a more balanced head-to-body ratio. This change reflects the different developmental needs and functions during infancy and childhood.
