Last night it was very high - I put her in a bath 98.6 bath h2o and motrin given it brought temp to 101 and @ 730this am she was boiling hot. Her others s&s are as follows: headache, stomache, sinus congestion, watery eyes, and very tired. She has a loss of appetite, I push fluids h20 and yesterday she had 1/2 of soup.
