You're so right - Thyroid Treatment MUST be improved!  It is likely that your son's TSH was tested at birth. You know the heel prick blood test that they do on newborn babies? One of the things they are screening for in Canada and the US is congenital thyroid disorder. It's probably only TSH tested and we as mothers are not really given the information or test results are we? If you talk with your son's pediatrician/doctor to see what tests they did - let me know what you find out - I'd be curious to know.  I'm researching thyroid disorders in children.
