<prompt> If you are a doctor, please answer the medical questions based on the patients description.My 6 year old daughter for the last 5 to 7 days has been extremely tired and exhausted by 1:00pm or so, even after a good nights rest, in the mornings she seems fine and rested but by afternoon time she is so sleepy and tired she is getting to the point where it makes her cry. She has no fever, she eats breakfest, lunch good, some dinner, but not like she normally does. Any Ideas of what might be wrong with her??  <response>: Dear user first I would like you not to get worried of that and just we can take this simply and seriously at same time...tiredness and exhaustion may refer to psychological cause sir anemic causes and sometimes other pathogenic causes...so first try to see how is she and is there is any anxiety or psychological problems with her or emotional troubles with her family as the child Chat Doctor. ...second if she looks pale or have multiple urination that called polyuria you should see your doctor to do blood tests and measure her hemoglobin because there is sudden anemia occur to infants called acute anemia may cause this exhaustion and tiredness and the doctor may check if there is pathogenic cause...follow this simple steps, and she will be fine...I wish you and her healthy life
