Can anyone help? My 2 year old son was ill about 4 weeks ago with a cold/cough. Although he got better, the cough lingered and he is now really bad again with bronchitus. I took him to the Doctors yesterday and she gave me a prescription for anti-biotics but suggests I leave it a day or 2 to see if he gets better by himself before starting the course. He's never had anti-biotics before and I understand the importance of leaving his own immune system to fight the virus, but how harmful would it really be to give him the course? He's really run down with ulcers in his mouth and not eating properly, so I can't see him being strong enough to fight the virus himself. I just want to get rid of it once and for all but don't obviously want to do what is going to be best for the long run.
