Summarize the following:
Observe your daughter’s chest area when she’s 9 or 10, which is often when girls start thelarche, or developing breasts.  Ask your daughter if she’s felt nickel-sized lumps under each breast called “breast buds” or noticed any pain or tenderness in her chest.  Bring up breast buds with your daughter gently and constructively. For example, “Hey Kate, Mrs. Allum mentioned that Devon is getting breasts. You know it’s completely normal if you have or haven’t yet. You might feel little lumps on your chest called breast buds. They don’t hurt and just mean you’re getting your breasts, too. You can ask me questions any time you have them. I’ll keep it between us.” Be aware that each breast bud can develop at different rates, which is completely normal. Girls usually start puberty between the ages of 8 and 13. Recognizing signs your daughter is going through puberty can indicate that she may be ready to buy her first bra. Watch for the following signs that your daughter is going through puberty:  Changes in body shape. Development of body hair. Changing behaviors and emotions. If you don’t notice any signs of breast development or your daughter is shy, schedule an appointment with her doctor. Allow your daughter to talk to doctor by herself. They can then call or meet with you to discuss her development. Ask if they think your daughter needs a bra and how to broach it with her.

Summary:
Check for breast buds. Look for other signs of puberty. Talk to your daughter’s doctor.
