You can be sure the child knows that something is wrong, and, since they have wonderful imaginations, they often believe things are worse than they really are.
Since a child's world revolves around the child, they tend to believe that when something is wrong, it's their fault. It is imperative that they know that's not true.
The purpose here is to be sure the child knows that the progress of the illness is not her responsibility, while suggesting that a somewhat different behavior might be in order under the circumstances. This must be done with great delicacy, lest the child feel that Mom's recovery is dependent on how the child acts and -- if Mom gets worse -- believes it is her fault.
It feels good to help -- ex. bringing Mommy a glass of water.
The goal of starting the conversation is to open the door to questions and to vent their feelings. The more they know, the more they will feel like part of the family. Listen carefully to what they have to say and answer the questions as honestly and openly as you can, given their capacity to understand.
It is sometimes too difficult for the ill person or the spouse to tell the child, and therefore it might be best handled by a friend or an older sibling or an uncle or aunt. Perhaps after the original talk, other members of the family should also be relatively frank with the child about the illness.
This is a true statement. The American Cancer Society reports that there are 8,000,000 in the United States today, to whom cancer is a memory.
This is extremely important, since children very often know enough to assume that, because Mom has cancer, they or someone else in the family will catch it.
The child is likely to feel neglected, unless this point is made clear to her time and time again. How often depends on the age and emotional maturity of the child.
Although the child's life will not be exactly the same as before the diagnosis, for all the obvious reasons, the child should continue to lead as normal a life as possible.
Other members of the family might also talk to the child about the household situation. (See #3 and 5, above.)
