With the release of the2025 updated growth charts, parents now have more reliable references to better understand and monitor their children’s physical development. Every parent hopes their child can grow up healthy and tall, but in reality, the process and speed of growth vary from one child to another.

This helps create the optimal environment for growth, supporting children in achieving their ideal height goals.

What is a Growth Curve?
