The purpose of this study is to understand how having a heart problem affects development,quality of life, and family life in young children and their families. Results for children and families with heart disease will be compared to children and families without heart disease. The investigators hope that this information may help us to support children and families better in the future. All children and families that are seen in the HHC Developmental Follow-Up Program will be asked if they would like to take part in this study. It is hypothesized that children with congenital heart disease will demonstrate developmental delays when compared to normative values.
