Question 1

what is the average head circumference for a 6 month old girl?

Accepted Answer

It is just a number: Around 42 cm (16-17 in). The number is somewhat meaningless from a medical standpoint... sort of like hair color. If one asks, "What is the average hair color of a 6 year-old girl", the answer is a meaningless color. Head circumference percentiles are compared to the percentiles of the parent's head sizes. Thus, if the parents have smaller heads, we don't worry about their babies' smaller heads.

Question 2

head circumference of 15 month old baby boy is 50 cm.is this normal?weight 11 kg and length 78 cm

Accepted Answer

No: If properly measured it is above the 98% mark for age. Weight is about 75% and length 50%. I would want measurements of both parents HC (it is often an inherited feature) and a further evaluation that is beyond the scope of this post.

Question 3

me and my husband both have small head but my 2 month old baby have 85 percentile head circumference is that normal?

Accepted Answer

Yes: If your baby is growing fine and following his growth curve steadily, shouldn't be a problem, but keep the follow up and measurements, he or she doesn't need to be the same as you parents, enjoy your baby

Question 4

1 month old head circumference percentile went from 70th to 90th in 2 weeks. doctor says his head feels normal & looks normal so most likely it could be measurement differences since it was measured by 2 different people. is this normal or worrying?

Accepted Answer

: You asked a separate question with the exact measurements at birth and at one month old. The current head circumference is still below the maximal circumference so you have nothing to worry.

Question 5

my daughter was diagnosed with having craniofacial dymorphism. what is that? her head circumference is 21 inches. she is 6 years old. is that normal for her age?

Accepted Answer

: This is just a label used to describe a person whose skull and facial features differ from what is considered normal values. It may be seen with chromosomal abnormalities, gene defects or as a variation of normal. Physicians often choose to do extra tests to separate the normal variants from those who need special monitoring for hidden abnormalities that may affect their health.

Question 6

neurologist report for 7 yr old says she has flat mid facies. what is flat mid facies? ent doctor checking to see if adenoids have grown back? head circumference is 53.8 cm. is that normal for her age?

Accepted Answer

: Flat mid facies means flat midface in lay term. A 53.8 cm head circumference for a 7 year-old-girl is at + 2 standard deviation of a mean size, i.e. your girl's head is big but not quite out of normal size. Your daughter has been evaluated by several specialists so you should pose these questions to the specialists.

Question 7

my baby is 1 month old and her head circumference is 39cm should i be concerned?

Accepted Answer

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!

Question 8

my son is 2 months 2 weeks old his head circumference is 41 cm he weighs 14 lbs is that normal?

Accepted Answer

Yes but ...: It is difficult to measure HC exactly but those numbers are well within the normal range. Just enjoy playing and talking to your new child!!

Question 9

hello my baby is 2 months old and her weight is 4.6kg and her head circumference is 38.5cm is that normal.

Accepted Answer

Depends: She should follow a growth curve based on her birthweight head circumference, weight and length.

Question 10

my 2 month old dropped in both head circumference and weight percentiles at 9 week appointment. hc went from 38th to 13th and weight from 58th to 34th. is this a sign of impaired growth or just leveling out?

Accepted Answer

: Failure to remain on a consistent growth patter suggests either a nutritional problem or a medical one. If this decline persists through the next check-up, I would want to do some testing. Please review this with his doc.
