What does my baby's percentile mean?

Growth charts are a great way for you and your doctor to compare the growth of your baby over time, and compare them to other babies of the same age; whether here in the US with the CDC growth charts or all over the world with the WHO growth charts. You might be wondering what it means if your doctor says your baby is a certain percentile. The great way to do that is to imagine a room with a hundred babies the same age as yours; all normal; all healthy, but there would be a natural variation, some would be bigger than others, so if your doctor says your baby's weight is the twenty-fifth percentile, you can imagine that in that room of a hundred babies; the same age as yours, your baby would weigh more than 25 of those babies and less than 75. This is a great way to compare your baby with other babies of the same age. It's also a great way for your doctor and you to follow your baby's growth over time and the rate that they are growing. We would worry if a baby's weight would start to flat-line or not go up at the rate we would expect, or if they were starting to cross the percentile lines and be growing too fast.
