Baby's Puberty at 10 Months: Mom Explores Egg Freezing
26 Sep
Summary
- A 10-month-old girl was diagnosed with central precocious puberty.
- Her mother is considering egg freezing due to fertility concerns.
- The child faces bullying over hormone-related skin spots.

A young girl named Sienna, from London, received a diagnosis of central precocious puberty (CPP) at just 10 months old. This condition means her brain initiated puberty signals much earlier than typical.
Sienna's mother, Sophie Dumas, noticed enlarged breast tissue, leading to extensive tests. These included distressing stim tests and X-rays to determine Sienna's bone age. Thankfully, an MRI ruled out any underlying brain abnormalities.
Now five years old, Sienna undergoes regular four-week injections of a hormone blocker. Without treatment, she would have entered puberty years before her peers, potentially impacting her adult height and causing significant emotional distress.
Sophie is now exploring the possibility of egg freezing for Sienna. This is to safeguard her daughter's future fertility options, as the condition or its treatment might affect her ability to have children later in life.
Sienna is also experiencing hormone-related skin spots, leading to bullying at school. Sophie is determined to help her daughter navigate these challenges and preserve her childhood innocence.
