Early Puberty in Girls: What Parents Need to Know

You’re not imagining it. Girls are getting their periods earlier. Some start breast development before third grade. That shift can feel startling, especially when a child’s body starts looking older before they’re ready to be treated that way.

The medical term is precocious puberty, and it usually means puberty signs show up before age eight. That might include breast growth, pubic hair, or a sudden growth spurt. If a period starts before age nine, it’s definitely worth flagging.

Why is this happening more often? Researchers point to multiple factors: changes in body composition, stress, certain household chemicals, and even environmental toxins. The truth is, we’re still learning. But what we do know is this: early puberty changes more than just the physical body.

Kids going through early puberty are more likely to experience anxiety, body image issues, and mood shifts. They may also have shorter adult height due to bones maturing earlier. And they might feel out of sync with their peers, emotionally and socially.

This isn’t your fault. It’s not about doing anything wrong. But you can help by getting support early. Pediatricians might monitor growth patterns, run hormone labs, or refer to specialists. And you can help your child understand what’s happening in a way that doesn’t feel scary.

Puberty doesn’t come with a manual. But we’re here to help write one that actually makes sense.
