Keep a close eye on your child’s diet to make sure they get enough calories to heal and grow. After heart surgery, most babies and infants (younger than 12 to 15 months) can take as much formula
or breast milk as they want. Sometimes the doctor may want your baby not to drink too much formula or breast milk. Ask your child’s doctor any other questions about your child's nutrition. Limit feeding time to around 30 minutes. Your child’s doctor or nurse will tell you how to add extra calories to formula if it is necessary. Toddlers and older children should be given a regular, healthy diet. The doctor or nurse will tell you how to improve the child's diet after surgery.
