Yong Yan, Well, My son is 14 months old and is 30 inches long and 30 pounds. Sorry I don't know the metric numbers. He likes to eat. I give him 1/4 to 1/2 of a teaspoon a day. When I said table salt, I meant the kind of salt that we use at the table. Just plain ordinary salt. Sorry about that. He gets 3 ml of the Cortef a day so that's 6mg of cortef and he gets 1.5 ml of prednisone at night whch is just a stronger type of Cortef. Mainly the only way that you will know if your daughter is getting the Cortef she needs will be by her blood tests from her doctor. If she doesn't get enough she could eventually get sick and have an adrenal crisis. If she gets too much she will get puffy and have weight problems. It is difficult, but try to trust your doctor on the dosage. Maybe if they haven't, you might want to ask them to explain all about the blood levels and her tests she has done so you can know what an "acceptable" level of 17 OHP (hydroxyprogesterone) and Renin and Testosterone is. I hope this answered your questions. Feel free to e-mail me anytime!! Samermk@aol.com
