My 1 yr old son has developed a fever since morning.he is running a temperature of 100-101F since 11 a.m. he is very whiny and tearful and less active than normal.He had no cough or cold,šuddenly he got the fever. a similar incident of fever occurred about 3 weeks back, which lasted for a day. it was preceded by a bout of loose motions for 4 days. no medication other than paracetamol was given. for the past 2 weeks he has been passing stools 2,3 times daily, every time he takes his meals. But the consistency of the stool was normal. But today he has not passed stool at all.also for the past two weeks he has been tugging at his ears at night but no major bout of crying occurred.
