 [ Symptoms ] my 3 yo son has a fever of 102 103 for last 2 days when should i take him to the hospital if the fever does not go away no other symptoms he is drinking fluids and eating very little [ Disease ] i am not a doctor just another mother my kids are now ages 27 21 and 16 i would take my children to the doctor pretty quickly within a day or so for fever as high as 103 degree f although many times the dr would say it was something that would pass on it is own and just to provide fever medication and make them comfortable i never wanted to take a chance that it was something serious that we could catch early i would consider the following does the fever reduce with medication if so than you can keep it under control for now if not you might use that as criteria to go on in is the child drinking normal amounts or more if so that is another good sign fever can really dehydrate someone if heshe refuses fluids can not keep them down or is drinking less than normal again i might use that as criteria to take the child in i never used eating as a criteria while a child had fever as long as they could keep something down and would eat a little other mothers may disagree with this this last bit is what my mother a registered nurse told me if in doubt call or take the child in you would rather err on the side of caution when it comes to kids
