well from my experience when i was in first grade i got somenella and when my fever reached 105 i had convulsions. i wrap my kids feet in cold rags and rags behind their neck and on their forehead. along with motrin it usually works.
my 3 y/o son has a fever of 102-103 for last 2 days when should i take him to the hospital if the fever doesn't go away. no other symptoms he is drinking fluids and eating very little.
