Why do we have bones?
Bones are your body's strong frame, so you can stand up tall.

Pip’s answer
- Bones are your body's strong frame, so you can stand up tall.
- Some bones are like helmets and shields, keeping your brain and heart safe.
- Muscles pull on your bones to help you run, jump and wave.
- Ooh, your bones are alive and grow bigger right along with you!

Can you stand up super tall and strong, buddy?
For grown-ups
Bones form the skeleton, which supports the body, protects organs like the brain and heart, and works with muscles to move us. Bones are living tissue that grows and repairs itself. Babies have around 300 bones; many fuse as we grow, so adults have 206.
Ask your child: Can you feel some of the bones in your hand?
