HELP> My lovely grandson who is 6 months has been ill for the last 12 days. Temperature up and down to 38.5 Calpol helps for 2 hours only and being sick too. He was taken into hospital 3 days ago and is confusing all the doctors. His ears, throat, urine etc are fine, he has had a chest xray - fine, my Son insisted on a blood test which has found infection but they dont know of what and will not give him antibiotics at 6 months, he was sick in the night again and temperature was high again!! Anyone got any ideas, he is fine in between bouts of temperature and sickness and the doctors admit to being baffled?? Help we are all really worried.
