Hi, Head circumference is measured with a non-stretchable tap across the most prominent points on front and back of head-part of forehead about 1 finger breadth above eyebrows and occipital protuberance (the bony prominence on back of head). After 6 months, we expect an increase of 0.5\u00a0cm per month. For a baby with normal size at birth, we expect 44.5 at 9 months. To decide whether the increase is significant, we have to compare with that at birth, and plot on standard chart. Your doctor will discuss with you. Hope I have answered your question. Let me know if I can assist you further.
