What is Head Circumference and Why is it Important?

Head circumference is the distance around the widest part of a child's head, usually measured at the forehead. It's an important indicator of a child's overall health and development, as it can affect their brain growth and cognitive function. A child's head circumference typically increases rapidly during the first few years of life, and it's essential to track this growth to ensure they're developing normally.
