Well they would been categorizing your baby in the 15th percentile of something. It could be that your baby is in the 15th percentile of above average weight gain, growing, motor skills, etc.
For a complete definition of Percentile see the related link. A percentile is the value of a variable below which a certain percent of observations fallThe 90th percentile is typically the point at which 10 percent of the highest scores fall.If you assume that scores are out of 40, and that they are evenly distributed (an unlikely event in real life), then the 90th percentile is all scores above 36.
If you wish to determine if you are overweight the following information may help:The following is the typical information that is used to determine if a child is underweight, normal weight, overweight, or obese; you must start with a children's weight chart, in which you simply plan/plot your height, BMI (Body Mass Index) and weight to determine where you fall with others children of your age group.Now to determine if you are underweight, the BMI should be below the 5th percentile; if you are of normal weight, the BMI should be at the 5th percentile but less than the 85th percentile; if your are overweight, the BMI should be the 85th percentile but below the 95th percentile; and finally, if you are of obese weight, the BMI is at or above the 95th percentile.
40 percent of people score less or are below you and 60 percent are above.
140 and above are genius or near-genius. 129 is at the 97th percentile.
The 20th percentile is an estimate of the value in which 20% of the observations should fall below this value and 80% should be above it. Methods vary on the calculations, but all methods will give similar results if there are a large number of values. See: http://en.wikipedia.org/wiki/Percentile

90th percentile is simple another way of saying that 9% scored above and 90% scored below (the other 1% being the number 90). For example, if you take a type of standardized test in high school, if you do well, you are at the 90th percentile, meaning 90% of students scored lower than you and 9% scored better. You can not be in the 100% percentile, because you cannot score better than yourself.
