Make one's bones

You know how when you are born, you have tiny, soft bones in your body? As you grow up, these bones become bigger and harder. This is called making your bones stronger.

Just like how a plant needs sunlight and water to grow big and strong, your bones need good food and physical activity to grow big and strong. Eating food with calcium, like milk and cheese, helps your bones to become stronger. Playing outside with friends or doing exercises like jumping, also helps to make your bones stronger.

When you make your bones stronger, it makes it easier to play sports, run around, and do all sorts of fun things. It’s important to take care of your bones because they help your body move and stay healthy.
