My sons 5 months, he has fevers of 100.3 to 101.1 for the past 4 days only goes down with tylenol but after 4 hours it's back up. He also has an ear infection, conjunctivitis, a really bad cold and hes throwing up. He's not having more than 2 wet diapers a day he's been seen twice and the doctor agreed he's dehydrated but since he's on medication they're not doing anything else. I've tried it all from water, apple juice, pedialyte I dont know what else to do please advice
