Julia SHi Heather,
It’s really hard to compare the dose of those with CAH for different factors. Those with CAH do make some cortisol and that amount is a factor, so are weight and metabolism. My daughter is on 2.25 mg per day at age 3 1/2, she weighs 38 pounds and is about 3’ 3 1/2". With that said, when she was 4 months old she was on 7.5 mg as a tiny baby. We switched endos and the new one immediately put her on 3 times a day (instead of twice) and lowered her dose. She started showing less signs of oversuppression. then we went to 4 times s day and even less dosage with the circadium rhythm dosing. This has worked best for her and has allowed us to lower her dose. I guess I’d wonder what her levels show, and if she has any oversuppression symptoms: chubby face, weight gain or slow growth, sleeping less, cranky....among others. Good luck with this. Julia
