Question:
My 6mo. old daughter has a large head. It has been growing normally and consistently with her height and weight. She is in the 80% for height and weight and the 95% for head circumference. She seems like a normal baby, passing the normal milestones...That being said, I *think* have a big ol' head myself. I have looked everywhere to try and find an adult head circumference chart. Can you please provide me with some information? I am looking for averages. Are there any issues with her head being in the higher percentile over her H&W? Should I be worried?
Thanks!
Answers:
I understand your frustration. I've been looking for the same data, without much luck. The only paper I found remotely related was:
Growth in head circumference from birth through young adulthood. Dorothy Eichorn and Nancy Bayley. Child Develpm., 1962, 33,257-271.
But the study is very small (15 adults for girls and 14 for boys). Anyway, the mean was 57.99 cm for boys, and 55.81 for girls (25+ years old). For a 6 mo. old baby girl, the mean was 43.34 cm (average of 37 baby girls). I hope this helps.
I think this site will help. Scroll down and you will find links for head circumference based on sex and age. Click the one you want. they are printable too.
