Newborn Head Softness: Fontanelles and Skull Development

A newborn’s skull consists of soft, flexible plates separated by fibrous sutures and fontanelles (soft spots). This allows the head to mold during birth and accommodates rapid brain growth. Plates gradually fuse; by age 2, the skull is fully ossified.

Clinical Significance

• A sunken fontanelle may indicate dehydration.
• A bulging or hard spot could signal increased intracranial pressure or skull fracture.

The softness protects both baby and mother during delivery and supports early brain development.
