Infants increase their head circumference by 12 centimeters during the first year
of life as they start with an average of 35 centimeters and end up with an average
of 47 centimeters.
To remember the rates of increase at various months of the first year, we can use
the above mnemonic;
*It means that during the first three months infants will gain six centimeters
increase in OFC (occipitofrontal circumference) which means 2 centimeters per
month.
*The next three months the rate is three centimeters in three months which means
1 cm per month.
*The next six months the rate is three centimeters in six months which means 0.5
cm per month. |
