hello my granddaughter is 18 months old in daycare 5 days a week. She has been sick on and off several times since last December cold pneumonia running nose. She has had a high temperature 2-3 times as high as 104 degrees but when given Tylenol fever goes down and then she is ok. What causes a high fever like this then goes away. She is otherwise healthy and happy.
Thanks for putting up your query at Chat Doctor. I understand the cause of your concern for your 18 months old granddaughter. There can be a number of causes that causes high fever. The most common of them is infection which may be viral or bacterial. Typhoid is a very common cause of high rise of temperature where the temperature hardly reaches baseline. But that also varies with geography and I do not know where you are located. Urinary tract infection is also a very prevalent cause of high fever in child Chat Doctor.  The cause of fever needs to be investigated thoroughly especially because it is recurrent. Please consult your pediatrician and do not self-medicate. I hope that helps. Feel free to revert with further queries if any.
