How can a child with spasticity explain the condition to peers?

Spasticity is when my muscles get really tight, like they’re trying to pull together all the time, even when I don’t want them to.

Imagine if you were trying to move your arm, but it feels like it is stuck in cement and hard to move because the muscles are holding it too tight.

Sometimes, it makes things like walking or picking up things harder, but I’m doing exercises and getting help so it gets better and easier.
