my daughter age 9 5mg-5mg-5mg, 67lbs 54" (as I stated above) has never been on the liquid form, always the tablet form from age 18 mo, and before that was on IM injections, my endo never trusted the suspension. I do think that the dosage is dependant on the child, not all 9yr olds will take the same amount. But I do think it is funny/strange that some are taking more than twice what other of the same age are taking. I am glad this string got started.
