**BOND Study on Breastfeeding and Heart Health** This study looks at how breastfeeding directly from the breast, called **Direct Breastfeeding (DBF)**, can help babies with **Congenital Heart Disease (CHD)** and their moms. CHD affects the heart from birth. They want to see if DBF can improve health and bonding between moms and babies. The study will happen at many hospitals. Some hospitals will try new ways to help with breastfeeding, while others will continue usual care.
