The head circumference of infants and young children is a parameter that shows the level of development and growth of the child. Therefore, parents need to check periodically, especially in the first years of life to have appropriate treatment.

The development of infants and young children is extremely rapid, changing every day. Therefore, parents need to have knowledge of "normal child development" to have appropriate care and take their children to see a doctor promptly if there are abnormalities.

Fetal head circumference is one of the important indicators that helps assess the level of fetal development and detect abnormalities in the baby while still in the womb. This helps reduce the risk of birth defects in children, especially microcephaly.
