Effects of Mother-Sung Lullabies on Infant Pain and Maternal Anxiety

"Approximately 15 seconds before the vaccination, each baby's mother began to sing a lullaby. Infant's mother continued to sing lullabies until all the vaccinations, which were given immediately after the BCG vaccination, were completed. Each mother touched her baby's hands and body while singing a lullaby and hugged her baby after the procedure. All the mothers sang the same lullaby, Sleep and Grow. Mothers were reminded of the words to the lullaby before vaccine administration."
