Staying at a healthy weight is important for children’s bodies as they grow and develop.

A healthy weight can usually be maintained by balancing the amount of energy your child takes in (through food and drink) and the energy they use (for growing and through physical activity).

No two children are the same, but there are some basic guidelines around children’s weight. 

Body mass index (BMI) is used to assess whether a person is underweight, a normal weight or overweight. BMI-for-age charts are recommended by the National Health and Medical Research Council for assessing children’s weight. 

These charts recognise the fact that children’s bodies are still growing and developing.
