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

if your kid is shorter or the head size is increasing faster than his length, it is unusual. If this is a girl the head is too big. ...Read more

My baby is 1 month old and her head circumference is 39cm should I be concerned?

My baby is 1 month old and her head circumference is 39cm should I be concerned?

So far, just enough: To have close monitoring by her pediatrician. That is in the above 90% range but checking for other sign and progress is the correct action to take. I hope everything else seems okay so that this can be explained and/or addressed easily. Don't worry - just have a good full exam done. Best wishes to you and yours! ...Read more

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?

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 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.

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? This condition can be associated with rapid "catch up growth" In some cases, familial macrocephaly accounts. Speak to your pediatrician and ask to see the head circumference chart, so you can understand what is happening. ...Read more

I m concerned for baby head growth. She is 18 days old. Born with 37 CM head circumference today 40 cm. Is that normal.

Large head: 40 cm at 18 days is large. IF there is no bulging of the fontanelle, the difference may be due to molding durign the delivery. Was this a large baby? Is there a family history of large heads. If there is any concern, speak to your pediatrician andi f necessary have an ultrasound done. ...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

One cm a month: One centimeter a month of infant head growth is just about right! Here are the charts we use here in the US to evaluate head growth in babies.

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

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

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
