The interventions in the appearance of the body began from the first days of birth, when they began to shape the head for aesthetic and religious purposes. At the age of three, boys were placed a white bead on the crown of their heads - a symbol of their immaturity to have contact with the sacred - and for girls, a red shell was placed on the pubis - possibly associated with infantile sexuality -, and from this point onwards, the boys wore panties and the girls wore skirts, since before they only covered themselves with a mantilla. The bead and the shell were removed until they were thirteen years old during the puberty rite, ka'put zihil.
