"Kun U Khun Mingala" () - the Feeding of the First Betel ceremony was held about 75 days after the birth of a prince or princess to bolster the newborn child's health, prosperity and beauty. The ceremony involved the feeding of betel, mixed with camphor and other ingredients. An appointed official () arranged the rituals preceding the ceremony. These rituals included a specific set of offerings to the Buddha, indigenous spirits ("yokkaso", "akathaso", "bhummaso", etc.), Guardians of the Sasana, and to the parents and grandparents of the child, all of which were arranged in the infant's chamber. Additional offerings were made to the Hundred "Phi" (), a group of 100 Siamese spirits headed by Nandi (), personified by a Brahmin figure made of kusa grass, which was ceremonially fed scoops of cooked rice with the left hand.
