Relative study: His rating means that 10% of infants at this age have a larger head circumference (size) while 90% are smaller.If the size has increased from 25-50-75-90% over several months it would suggest growth was too rapid.If usually in that range, it just means the kid has a big head.It hasn't bothered me any, except for having trouble finding a helmet/hat that would fit.. ...Read more

I know a person's face can gain or lose weight, but is it possible for their head circumference also?
My daughter is five months old now and her head circumference is 42cm, does it imply she has a big head?
No, it's 50th-75th : %ile, depending on use of the who or cdc growth charts. More important than size ( within the normal range) is velocity of head growth, which reflects brain growth; i.e., is it ?ing rapidly, dropping off or following a growth curve? The aap recommends developmental surveillance with standardized screens at each check-up. See the aap healthy child app & firstsigns.Org for details. ...Read more

My daughter head circumference was 33 centimeters at 3 weeks now its 36 centimeters at 1 month is that normal?
Many variables: Heads/Brains grow rapidly at this age but growth isn't the only variable when considering head circumference. The measurements could vary if it wasn't taken exactly the same way. When you follow up for the 2 month visit, your Pediatrician will plot another measurement on a growth curve and compare it to prior records. As long as your baby is feeding/acting/developing normally, I wouldn't worry. ...Read moreSee 2 more doctor answers
What does it mean if a baby's head circumference percentile drops from 90 to 75 at 5.5 months? Does it indicate intelligence levels?
Head size: My first thought is technique and is a measuring error. That's the most likely. I would get it measured again and monitor it over the next few weeks to see if it is real or to watch the trend. Premature closure of the soft spot is a possibility which is fixable. Lower IQ would be unlikely. Talk to your doctor and let him know your concern and work together. ...Read more
My 18mo son is always on the lower end of percentiles, except head circumference. Is this an indication of his future height and weight?
Hard to say: The best predictor of how a male is growing and where they will end up is their parents. Final height is expected to be the average height of the parents plus 2.5 inches. Body frame and muscularity also tracks as a blend of both parents, with more features contributed by the parent of the same sex.Since I do not have any details, the answer must remain very general. ...Read more
Hi my 9 week old sons head circumference measures 16 inches he weighs 11pounds 8ounces, is that in the normal range for head measurement.
Head circumference: A head circumference of 16 inches at 9 weeks places him at the 95% for his age and sex. This is considered normal. I don't have a height, but his weight is about the 85%, so it seems from that he is generally a big boy. The more important factor, however, is interval growth from visit to visit. If he's always been at the 25% and suddenly is at 95%, that's more concerning than if he is always 95%. ...Read more
My baby was born with a Head Circumference of 31.75 CM and at 3 month his HC is 36.9 cm. is the growth normal? Please advise and thanks a ton.
Speak to baby's doc: That is a rapid rate of growth in 3 months. The usual rate is 1 cm per month for the first 6 months. Was your baby small for gestational age?

Speak to your pediatrician and ask to see the head circumference chart, so you can understand what is happening. ...Read moreSee 2 more doctor answers
