Here's what you should know:
* Breast development is a natural part of puberty: It's a sign your body is getting ready for womanhood.
* The timing and speed of development vary: Some girls start puberty earlier than others, and some grow faster than others. This is perfectly normal.
* Comparing yourself to others is unhelpful: Everyone's body is unique, and focusing on comparisons can be damaging to your self-esteem.
Instead of worrying about size, focus on:
* Talking to a trusted adult: A parent, guardian, teacher, or doctor can answer your questions about puberty in a way that's accurate and age-appropriate.
* Taking care of yourself: Eating healthy, getting enough sleep, and exercising regularly can help you feel your best.
* Celebrating your unique body: Your body is amazing and deserves to be treated with kindness and respect.
Remember, your body is perfect just the way it is! If you have any concerns or questions, please don't hesitate to talk to a trusted adult.
