What does 90% percentile in infant head circumference mean?

What does 90% percentile in infant head circumference mean?

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

Is a 23 head circumference size normal?

Is a 23 head circumference size normal?

Hope so: I suppose you mean inches in circumference.This is is on the larger size for an adult, but since mine is bigger, i think it is fine. It does make finding head gear that fits a bit harder. It would be a bit off the chart for a 3 year old. ...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.

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

10 week old baby length and weight both 85th percentile. Head circumference 95th percentile. Does this mean he has a big head in proportion to body?

10 week old baby length and weight both 85th percentile. Head circumference 95th percentile. Does this mean he has a big head in proportion to body?

Not really: I don't consider that difference worth anything more than noting. Big babies are big all over and this falls within the normal variation of such measurements. If the kid was 50% weight/length and 95% head, I would just measure the parents head to see where baby inherited it from. There are other issues to consider with a big head, but not from the reported info. ...Read more

17 wk old niece head circumference is on 99th percentile.50th percentile for height and weight.  Is this a problem? Her mother has quite a large head.

Probably fine: It's fine for an infant to have a large head, as long as it stays at a fairly constant percentile. It's only when heads grow or shrink too quickly that the child should be evaluated further. Make sure to talk with ur baby's pediatrician if u r concerned. ...Read more

Head circumference. : As long as the head circumference is tracking along the same percentile and with normal developmental progress, all that is needed is close followup with your child's PCP. Based on the information you provided, the head circumference is on the upper end of normal (~98th percentile). A family history of individuals with large heads, if present, make the head circumference stats less concerning. ...Read more

My baby weighs 9 lbs 6 oz at two weeks old what percentile is this on the growth chart ?

Full term?: If your baby was full term, this places him close to the 75% tile. What is important is his weight gain from birth. It takes more than 1 point on the curve to insure he is gaining weight. All the best. ...Read more

My baby girl's head circumference only grew by 1cm in 2 MONTHS, From birth (34.5 cm) to 2 months (35.5). Based on the head chart, she's way behind. ?

My baby girl's head circumference only grew by 1cm in 2 MONTHS, From birth (34.5 cm) to 2 months (35.5). Based on the head chart, she's way behind.   ?

Head circumference: This does seem like slow growth. Sometimes there is moulding of the scalp which alters the head circumference and sometimes it may be difficult to get an accurate measurement. Was your baby a full term baby? Are the other measurements, her weight and her height OK? Parents heads should be measured as well. Ask for a referral to see a Pediatrician or Pediatric neurologist to help sort this out. ...Read more

My 5.5months old baby had hie when born. His head circumference is always in 25th percentile, are there any chances for him to develope microcephaly?

My 5.5months old baby had hie when born. His head circumference is always in 25th percentile, are there any chances for him to develope microcephaly?

Difficult ?: I assume you mean hypoxia ischemic encephalopathy . If his head circumpherence is 25th% and stays on that curve that is good news for baby. The brain continues to grow and develop for 2 years so it is very hard to know if baby will have damage or not. Baby should be watched carefully and help given if does not develop normally. Mris may help to follow. ...Read more

Male puberty: Review of literature: mean stretch penile length at 1 year of age is 3.75 cm (+/- 0.54 cm) increases to 4.84 cm by late childhood then to 9.5 cm (+/-1.12 cm) by late puberty.

Nine month old head size 97 percentile, is that bad?

Nine month old head size 97 percentile, is that bad?

Depends: If it has changed from the 10% to the 97% since birth, I would be more concerned than if it was big all along. If his height and weight are on the larger side it would be more consistent with a normal variant. It didn't bother me much in life, except when looking for a helmet that would fit. ...Read more

9.7 mnth old has a head circum. of 44cm,47.3% range on growth chart.Is this normal?She babbles,crawls,pulls self up.Not much change from 6mnth appt.

Missing information: Head circumference is normal, near average, but we need the velocity of its growth. Head growth slows normally after 6 mos., but should plot along or near the same growth curve it's always followed. Strings of babbling at 6 mos. become non-specific " da-da, ma-ma" in 9th mo. Gross motor is good. Screens are on firstsigns.org. Follow-up with pede. & MS Early Intervention Program if concerned. ...Read more
