Hello
One of my aunts started at 9 and she talks about how horrible it was to feel young and the only one of her friends etc.
Great that you are talking to her about all the changes.
8 is a little early.. my sisters and I all started after 15!
More and more young girls are developing early--
on the rise is cysts and uterine fibroids that can cause major cramping -- (excess estrogen) with your history of endometriosis -- I would energize -- loveing the uterus and womanhood with your daughter --
I would eliminate all hormone induce food from her diet
Including Dairy and Meat(especially)
Drinking constantly from plastic water bottles throws off the estrogen as well -- A DIM product can help with this ...
If you already eat organic hormone free eggs meat and milk-- I would check her progesterone and estrogen levels --
( your OB can run a hormone panel test.)
All the extra estrogen in the food and water (birth control pills are released in the urine into the water supply etc)- Is a cause early development ---
Please feel free to email me with questions or a phone consult for more info -- on finding a balance .. ____@____.com
Be Well!!
