Summarize this article in one sentence.
It’s important to measure the child’s circumference at the widest part of the head. Set the tape right above the ears so it's nearly touching them and line it up on forehead so it sits over the brows. With the measuring tape in place above the ears and brows, wrap it around the back of the head. Be careful not to pull it too tight. Make sure the tape lays flat against the back of head where the slope is most pronounced. Overlap the tape slightly to get the most accurate measurement, and note the number.  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. To ensure that your measurement is correct, it’s a good idea to check your results a second time. Measure the head a second time -- and even a third -- to verify the measurement.
Place the measuring tape just above the eyebrows and ears. Pull the tape around the back where the head slopes up from the neck. Lay the tape where the head slopes up from the neck. Repeat the process to ensure that the measurement is accurate.
