Monitoring the head circumference of infants and young children is crucial for assessing their growth and development. Therefore, parents should check it regularly, especially during the early years of life, to ensure timely treatment if necessary.

Fetal head circumference is an important indicator, helping to assess fetal development, and at the same time detect abnormal signs of the baby right from the time it is in the mother's womb. This helps to limit the risk of birth defects in children, especially microcephaly.
