Nothing gives parents more anxiety at healthcare appointments than growth charts. For many parents, their child’s position on the growth chart is comparative to a grade on a test. So when they hear, “your child is below the 50th percentile” or “your child is falling off the chart,” they start to question not only the health and well-being of their child, but also whether or not they have failed as a parent. However, in reality, there may be nothing to worry about at all.
Growth charts were first developed in 1977 as a way to help health professionals determine if children were growing adequately. However, these charts have been updated over the years to make them more representative of all ethnicities, races, feeding styles, and socioeconomic statuses, since the original CDC growth charts were based on white, formula-fed infants.(1)
Today, growth charts are still frequently used by pediatricians and pediatric health professionals to make sure children are gaining weight, height, and head size appropriately. While growth charts can be helpful tools for health professionals, they are frequently misinterpreted by parents and caregivers with up to 77% of parents incorrectly interpreting children’s growth charts.(2)
All growth charts have percentiles that allow health professionals to determine how your child compares to other children their age and gender. For example, if your daughter is in the 75th percentile for height then she is taller than 75% of other girls her age.
While the specific percentile can provide some information, it is more important to pay attention to the growth trend over time. This is because it is more important for your child to follow their own curve than be at the 50th percentile. Just like adults have natural variations in height and weight, it is normal for children to be different sizes as well. In fact, only 1% of children will naturally fall on the 50th percentile, but this does not mean these children necessarily have any advantages over other children academically or developmentally.
It is also important to note that it is normal for children to cross percentile lines, especially in infancy.3-4 In fact, research has found that between 30-64% of children will cross at least 1 percentile line on their growth curve before 2 years of age.(3-4) This is likely because children are moving to the growth percentile where they are naturally or genetically supposed to be.
When determining if your child is growing properly, remember that the most important thing is for your child to be following their curve. If your child is naturally on the 5th percentile or on the 85th percentile, then that is perfectly fine! Growth charts are just averages, they are not specific to your child. Therefore, it is typically best to allow your child to find their place on the chart and follow their own curve.
If your child’s pediatrician does have concerns about their growth chart trends, then it is important to consider what could be contributing to this change in growth. There are many factors that can impact growth and development, including underlying medical concerns, trauma or loss, environment, or nutrition – to name a few.
Here are five ways that may help your child get back to their growth curve:
