hi, i have an 8 months old baby daughter, she was born 2 months premature, so really she is now about 6 months old, she has been running a fever for a couple days now, took her to hospital last night and while waiting, her fever broke, so we went home thinking its gone, tonight she is getting the fever back and has a greenish foul smelling stool with a fever and just out of the blue developed a red rash on her buttox and has some reddish spots on the back of her head. Any clue as to what this is please?
