Dunstan baby language was created by Priscilla Dunstan, an Australian opera singer. She observed that all babies make certain sounds just before they cry. According to Dunstan, learning these sounds can help you figure out what your baby is trying to tell you before their crying escalates. Dunstan is not a speech therapist or expert on babies, but she used her skills as a singer and vocalist — and her ear for music — to carry out research on babies around the world for eight years. The end result was Dunstan baby language. Dunstan baby language is more of a technique than a “language.” It’s simple for parents and caretakers to learn and apply to most babies.
