my 5-yr old is most unwilling to take any medicine prescribed to him by his PCP. I haven't found _any_ way to force him taking what he doesn't want. His will is so much stronger than mine, i suppose. Yet he loves to take Chinese traditional medicine, those coughing syrups.
And after i read those prescriptions' warning labels carefully, i tend not to force him and persuaded myself to 'Let nature taking care of it'.
