dilemma

Today, my son woke up with a runny nose. In day to day life with a young child who attends daycare on a regular basis, not all that concerning.  This is normal. However, as a person receiving treatment for cancer and knows, despite the "good drugs" that counter side effects, including increasing my white blood cells to normal levels despite the anticipated 30% drop caused by the chemotherapy drugs, I need to do everything I can do to prevent infection.  I know there is the option to send my son to the grandparents, but I don't want to. I know that he gets the most comfort from me and he is most comfortable with being home.  If it he becomes ill enough to be away from daycare, I suppose that is when I send him to the grandparents.  Thank God for family who live nearby and are fantastic supports.
