Why has your 4 year old got pubic hair?

If a 4-year-old has developed pubic hair, it might be a sign of precocious puberty, which is when a child shows signs of puberty earlier than usual. This can be caused by various factors, including hormonal imbalances or underlying medical conditions. It's important to consult a pediatrician for a proper evaluation and guidance. Early medical advice can help determine the cause and whether any treatment is necessary.
