I don't know anything about cah, except that my 4 week old son has just been diagnosed with it by his ped. He hasn't seen an endo, yet. But, I do have a 10 year old daughter who is very tall for her age. She was always a big baby, tall toddler and the tallest one in her class. She needed deodorant at age 7 and started wearing a bra at 8 and started her menses at 9. She is wearing a 36 b bra size. Her shoe size is 7 1/2. I am around 5'3 and her dad is 5'7. oh and she weighs 116 pounds. she doesn't look fat, just very solid. Could this be a from cah? We really watch what she eats. could it be late cah?
