We will conduct a randomized trial between the intervention of regularly showing children and their parents the peripheral blood smear and standard care, including reminders of the importance of compliance and review of complete blood count parameters, including WBC, MCV, and Hgb concentration. The outcome measures will be increase in hemoglobin concentration and %HbF and increase in perceived QOL. QOL will be measured with age-appropriate and parent/proxy PedsQL™. Medication adherence will also be monitored throughout the study with pharmacy prescription refills, physician assessment, and self-report via a visual analogue scale. Adherence estimates, hemoglobin concentration, %HbF and QOL will be measured at baseline, 3 months and 6 months.
