hi Chris:i thought your question from yesterday we back home.for my limit english.i can't experess my opinins all right.however i aslo faced this quesion through my observision(not according to endo's test,i know this isn't right).my girl was always about 20mg/S 9mg in winter,she had been stayed at home.although dose is so high,she ofcen expressed bad spirits ,such as vomit ect. from March i began to brign her out(home),she has good spirits,very active,has more energy .i decrese her cortef dose.from 9mg to 8.75mg to 8.5mg to 8.375mg to 8mg.i want deduce to 7.75mg 15.5mg/S.the reason i guess about :1.cortef has effect of diminish inflammation.baby easy ill in winter.part of cortef effect is to cure illness.2 cah baby aslo can produce corter.their produce less than normal baby.my girl cortef test is 1.2ug/dl (normal is 5-25ug/dl). as they grow.they produce more corterf(aslo less than normal baby)3.the lastest report about cah show:Asia baby is perfer to 12.5mg/S.(however at present,i don't dare to decrease to so low).4.as my girl grow i become to believe in science datas,as far as to liquid corterf i don't feel better.corterf in liquid isn't mixed well.i guess baby perfer to 16-18mg in winter.15-16mg is well in summer.i know all words lack of science affirms.hope you find real reason.BTW what do you according to think your Jack oversuppressed? i aslo hope to know your test result.i aslo feel bad for Jack,he is so young but draw blood so many times!good lucky to you.hope Jack grow well.yong yan
