OMG, well when my daughter was sick at that age (throwing up constantly) we were adviised to just gave her gatorade for 3 days straight...she took it okay, at least she was having SOMETHING. Jello is something to try too, because he does need the calories and to keep him from dehydration... poor little thing..if he is barely eating/drinking at all for long periods he needs to be admitted to the hospital, how accurate is your thermometer? Its possible that he DID reach 105 if your thermometer isn't perfect. I would call 104.7 105 and call the doctor to be honest! Good luck!
