Low Platelets are nothing to fool with, your daughter should be in a hospital being watched by Dr's. I went thru this with my daughter when she was 13 months old. We had to admit her to Vanderbilt childrens hospital, where they have to do differents blood test and do you know that with platelets so low she is considered a free bleeder. If she hits her head or anything on her body hard it can cause internal bleeding. If her pediatrician or dr is telling you this is nothing to be concerned with you need to get to another dr ASAP!!
