As parents, one of the most common questions we ask ourselves is: "Is my child growing normally?"

Growth is one of the best reflections of a child's overall health. But with so many numbers, percentiles, and charts, it can feel confusing. Let's break it down simply.

Growth Is More Than HeightWhat Are Growth Charts?When to CheckTakeaway for Parents

Growth Is More Than Just Height

Growth isn't only about how tall your child is. Doctors look at:

Height – how tall your child is for their age and gender.
Weight – whether it's balanced with their height.
BMI (Body Mass Index) – helps check if weight is appropriate for height.
Growth over time – the pattern matters more than a single number.

A steady climb on the growth chart is usually a sign that your child is healthy.

What Are Growth Charts?

Growth charts are tools developed from thousands of children's measurements worldwide.

From 0–2 years, we use the WHO growth charts.
From 2–20 years, we use the CDC growth charts.

When you see a "percentile," it tells you how your child compares to others.

Example: If your child is at the 50th percentile for height, they're right in the middle — taller than 50% of children and shorter than 50%.

When to Be Reassured, When to Check

If your child's growth follows a steady line on the chart — even if they're shorter or taller than friends — that's usually healthy.
If your child's height or weight suddenly jumps down or up across percentiles, it's a good reason to check with your doctor.

Takeaway for Parents

Every child grows at their own pace. The goal is not to "reach the top of the chart," but to make sure your child's growth is steady and within their expected range.

Growth charts aren't about comparison — they're about health, balance, and well-being.

With the MapMyKidz app, you can easily plot your child's measurements and track growth patterns over time, just like your pediatrician does.
