You can try using a metal measuring tape, but the metal typically doesn’t curve around the head as easily as a plastic style.

Measuring a baby’s head circumference can be important to ensure that their brain is growing and developing as it should. You can find appropriate growth charts for boys and girls on the Center for Disease Control’s website at https://www. cdc. gov/growthcharts/who_charts. htm#The%20WHO%20Growth%20Charts. If you’re concerned about the measurement, consult your child’s doctor.

Don’t pull the measuring tape too tightly around the head, or you won’t get an accurate measurement.
