A London mother says she is considering freezing her five-year-old daughter’s eggs after the child begins showing signs of puberty at about 10 months old. The reports describe how the mother, Sophie Dumas, did not initially recognize anything unusual until a health visitor noticed enlarged-appearing breast tissue.

The outlets say Sienna has been diagnosed with central precocious puberty (CPP), a condition in which puberty starts much earlier than expected. All sources attribute the initial discovery to the observation of physical changes during infancy and describe the diagnosis as a key turning point. While the stories focus on the early onset of puberty and the medical assessment, they also highlight the mother’s ongoing concern about the child’s future development.

The differing emphasis across the articles centers on the planned fertility preservation step: the mother’s consideration of egg freezing is presented as a response to her daughter’s diagnosis and the potential implications for long-term health and development. However, none of the sources present additional clinical details beyond the reported diagnosis and the mother’s stated intentions.
