I would need more information about inclusion for what. Children need to have information about life-threatening illnesses. Often when kids leave school having a diagnosis of cancer, it is very difficult to talk about this with the class. However, it is very useful to present information to them to make it easy for the child to discuss some of these things if they are comfortable with such questions. Today, many forms of cancers are curable, and children need to hear things like that.
Many children also wonder about things like is cancer contagious.
For young children, the knowledge about the chronic disease becomes a helpful and important issue. My son has juvenile diabetes. We are having a difficult time finding appropriate yet fun items for school lunch. Contact a dietician, and certainly your local physician could provide you with more appropriate suggestions. Children need help with this since many kids assume negative things often about disabilities or health problems.
