All my kids have just gone through this, temps of 40, nothing would bring it down nurofen and panadol combo only would get it to maybe 39. I am pleased to say after a couple of days it has broken, they are left with a shocking cough. I took them to the DR to make sure it was nothing more sinsiter but it is just a horrible virus that is going around. Its just awful.

Glad to here you little man is on the mend. Hope the rest of the house is spared.
