Educating yourself to your child's illness will help you regain some control of the situation and put you in the best position to be a strong advocate for your child. Doctors, nurses, social workers, and other medical professionals understand that sometimes information will need to be explained several times before it is understood. This is largely because parents are so shocked when they receive the diagnosis that a lot of the information isn't retained. Keep asking questions until you understand the answer. Take an active role in treatment.
Parents are an important member of the team that is working to make the child well.
Keep a journal of your child's therapy. Record information, especially when the child is home, and discuss it with the oncologist at your next clinic visit. Build a good relationship with hospital staff. Communication and trust is critical. Parents need to know they can discuss their child with hospital staff when they feel the need.
