Yes, what is it with Dr's saying it is not bad for a child to run a temp like that? Several of the people I work with have small children who have been fighting this creeping crud that is making it's way around and they all get a high temp - 103 to 104 and the Dr's just say to make sure they drink plenty of fluid (yeah when they aren't pucking it up) and they get rest. These poor kids are coughing their lungs up till they throw up.
Guess the hospitals are so full of patients they feel ones like these are still better off at home, like you said, until they dehydrate. Did your grandbaby end up in the hospital, or did they just give antibiotics and send a child with pneumonia home to get better?
Hang in there - spring is around the corner.
