Question
How should one handle a three-month-old baby with an abnormally large head circumference?
Answer
Typically, a three-month-old boy’s head circumference ranges from 38.2 to 43.4 centimeters, with an average of 40.8 centimeters; for girls, it’s about 37.4 to 42.2 centimeters, with an average of 39.8 centimeters. If the baby exhibits symptoms such as pain, crying, or a dull facial expression, it may be necessary to check for issues like hydrocephalus or abnormal brain development.
