The object traditionally symbolizing childhood’s end is the last doll, often called the última muñeca.
In the symbolic doll ceremony, the quinceañera receives a doll representing the toys and childhood she is leaving behind. The presentation may be made by a parent or another family member, and the doll can be specially dressed to resemble the celebrant. The custom is not performed at every modern quinceañera.
The last-doll tradition is often discussed alongside other symbolic moments, including the changing of footwear and the presentation of a tiara. These customs are regional and flexible rather than rules shared by every family. The doll is not intended to mark a legal change in status; it expresses an emotional and ceremonial transition.
