Research conducted in the United States shows that when parents kiss their children's wounds or sore parts, it reduces physical pain.
“let me kiss it and let it go”
It seems that mothers and fathers saying "let it go away" physically relieves the pain. When they fall, adults, including parents and siblings, approach the children with love and say, "Let me kiss it and let it pass." They want to relieve the pain with their love.
A study conducted at the University of Pittsburg revealed that parental touch reduces pain caused by different diseases in babies.
Parents kissing the child's painful area contains an important message for the child.
Researchers state that a child whose wound is kissed by his mother or father heals more quickly than one who is not kissed.
