Daughter just got her first period, will her body still change?

My daughter just got her first period at 12 and 3 months. She really is still very flat-chested and not curvy at all. Will her body still change? Me and my mother have larger breasts so I assumed my daughter would also. However, currently, she wouldn't even be an A cup. Does the majority of breast growth and change of body shape happen before the first period or after?

Yes, it will continue to change till 20.
Realize that all children before the age of puberty have minimal sex hormones in their body. It is with the onset of puberty and the pituitary gland starting up in the head that the sex organs are stimulated to then make their hormones; testicles make Total/Free Testosterone and ovaries make Estradiol, Progesterone (with ovulation), Total/Free Testosterone. It is with the Estradiol stimulation of breast, uterus and ovaries that the sex organs will be stimulated to enlarge. Thus growth of breast buds and then the stimulation of breast tissue is triggered by puberty as the body needs to have female hormone production in order to stimulate breast development. Then it’s knowing that the female hormones are properly balanced (a Progesterone/Estradiol dominance) and that ovulation is actually occurring on a regular basis. For more in-depth answers to questions that you may have about adolescence and puberty, please check out my book on Amazon; Blossoming, Becoming a Woman. This book gives an easy to read account of how the female body works and has many examples of patients who ‘tell their story’ as case studies in the book. This is the first book that I know of that actually is written for the teen and her parent and is meant to answer any questions that you have.
