DD11 has been taking it for about a year, and like others, it has been a miracle for our family. She takes 2 mg, and our pediatrician (who is pretty conservative) has told us that that is fine, but she shouldn't go over 3 mg. She she is growing like a weed, but our pediatrician thinks she has another year to go before menses. She previously had the same diagnosis as the OP's daughter, but it has now been updated to a diagnosis of ASD.
