A
Feedback:
This newborn is within normal parameters for head and body size. The newborn has a large head, averaging 13 to 14 inches (33 to 35.5 cm) in circumference. A short neck supports it. The chest is somewhat smaller than the head, 10 to 12 inches (25.5 to 30.5 cm) in circumference. The head usually measures 1 to 2 inches (2.5 to 5 cm) more than the chest. If the newborn was delivered vaginally, the head may show temporary molding (elongation) because of the overlap of skull bones during the birth process, but it is not larger because of this fact.
