Question 1

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

Accepted Answer

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.

Question 2

my 4 month olds head circumference went from 70th percentile to 89th percentile in one month. should i be worried?

Accepted Answer

Not necessarily: Variations in head circumference from month to month can be due to rapid rate of growth early in life or to measurement variance. If the baby appears not to be meeting age-appropriate milestones; loses tone, is intolerant of feeding, has fever or a bulging fontanelle, please have her or him evaluated immediately.

Question 3

should i be worry if the head circumference percentile always stay flat? for example, 50% at 1 month and 50% at two months?

Accepted Answer

No Worry: The "percentile" for head circumference is a reflection of your child's head circumference comparred to others, and it is best if the "percentile" does not change greatly.  50% at 1 mo and 2 mo means your child's rate of head growth is perfectly fine.  Concern only when head circumference increases/decreases by more than 2 standard deviations. Example: 50% at 1 mo, then 95% at 6 mos.

Question 4

what does 90% percentile in infant head circumference mean?

Accepted Answer

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..

Question 5

what does it mean if my daughter is in the 10th percentile for head circumference?

Accepted Answer

Population norms: Growth features including head circumferancee, length and weight have been collected over the years and publishes as basic guidelines for following growth in kids.The average of all would be at 50% while some would be on the larger or smaller size. The 10% means only that of 100 kids born on the same day, her head is larger than 10% but smaller than 90%.

Question 6

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?

Accepted Answer

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.

Question 7

my 18mo son is always on the lower end of percentiles, except head circumference. is this an indication of his future height and weight?

Accepted Answer

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.

Question 8

ive read that head size is proportional to height. my childs in the 97th percentile for height but only 30th for head circumference. is that something to be worried about?

Accepted Answer

Not really: It's more useful to follow the rate of growth of head.  In most of healthy infant, head circumference increases 1/2 inch per month in the first 4 months and 1/4 inch per month for the next 8 months.

Question 9

my baby was born with a head circumference at the 5th percentile, and now at 11 months its at the 95th percentile. is this rapid growth considered normal or is it worth looking into?

Accepted Answer

: I would likely do some form of imaging to look into the inside of the skull. Sometimes they can do a simple ultrasound through the soft spot if it is still present. If not a simple CT of the head would do. You did not mention any of the other body parameters, like length &amp; weight. If everything is in the same range other issues would need to be investigated.

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.
