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

See below: This is part of the tools that a pediatrician uses to gauge the growth and development of your child. A head should remain essentially at the same percentage as the child grows. Getting too large or too small is a sign of something wrong. ...Read more

Has the head circumference been growing at a rate parallel to the isobars on the head circimference chart, wven though it may be below the 5th percentile. Speak to your pediatrician about these issues. ...Read more

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

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

Small head circumference and low weight percentile mean failure to thrive?

Small head circumference and low weight percentile mean failure to thrive?

Depends: By definition, at least 3% of the normal population will grow along the smallest portion of the regular growth scales. Consistent growth along that or any percentile is not necessarily a failure to thrive. However;infants starting at the 25% & moving down to the 10% months later & heading toward the 5% in such measurements would be considered ftt because if the drop in growth rate. ...Read more

My daughters head is measuring below the 10th percentile. Is that healthy?

Depends: Head size is determined by genetics as well as other factors. If it has always been below the 10th percentile, is growing parallel to that line, she is developing normally and there are no other concerns then it may be genetic. If it started out higher and has been getting progressively lower on the percentile chart then she needs an evaluation. ...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

3 mo old w/ 1x2.5cm Anterior font and ridge in forehead, round head. Neonatologist carefully examined, measure, said not 2 worry. Is it normal?

3 mo old w/ 1x2.5cm Anterior font and ridge in forehead, round head. Neonatologist carefully examined, measure, said not 2 worry. Is it normal?

Yes, but: Anytime a parent has concerns about head size/shape, it deserves close monitoring because things change very rapidly at this age. The exam and measurements should occur monthly until all sutures have closed on the skull, usually 9-12 months of age. The ridge is likely the normal closure of the skull bones occurring, but needs to be monitored so it does not happen too soon. ...Read more

My baby girl had a head circumference of 34.5 CM at birth, and now at 2 months she  has a head circumference of 35.5 cm. Should I worried?

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
