Dunstan Baby Language

Have you guys ever heard of Dunstan baby language? I have just heard of it today from a post in Facebook. So I did a research about it and find it similar to Adel's cries. Haven't really tried it yet coz Adel is sleeping soundly now. So new mommies or mommy-to-be should learn this too, so we could understand what our baby is trying to tell us and save us from the hysterical cries. Note: not all babies have the same cries.
