Crying is more harmful to babies with congenital heart disease. All children cry, and normal children’s crying usually has no effect on their bodies. However, crying in children with congenital heart disease can increase the risk of infection or choking, leading to pneumonia and aggravating the child’s condition. Therefore, children with congenital heart disease need to avoid crying and choking as much as possible. If the child is crying a lot, try to calm the child by hugging and coaxing him/her to avoid increasing the burden on the child’s heart, which may lead to insufficient blood supply to the brain and vital organs, lung infection or other symptoms.
