In the ritual, the mother is honored and the child is blessed by the elders of the family and community. The father whispers the baby's name into its ear three times. The name is also written on rice spread on the floor or on a tray. The child's maternal uncle takes a gold ring dipped in a mixture of cow milk & honey and puts it on the baby's tongue.
