You have got to love the amoxicillin rash that can develop a good week into your antibiotic therapy. I have seen it a million times and on my own child it is hard. Oatmeal bath, benadryl, repeat...as much as both of you can handle. I know better not to go against the pediatricians recommendation, but I am NOT making him finish the last 3 days of the antibiotic and I AM saying he is allergic to this stink'n med.
