What is twelve babies at once?

Twelve babies at once typically refers to a rare occurrence of a multiple birth, specifically a set of twelve siblings born to the same mother during a single pregnancy. This phenomenon is extremely unusual, as most multiple births involve fewer infants, with the record for the most babies born at once being eight. Such an event would pose significant medical challenges and risks for both the mother and the babies. As of now, there have been no verified cases of a mother giving birth to twelve infants simultaneously.
