My 8 week old has had a cold for four weeks. He is absolutely fine during the day and very happy and content, but once he has been in his cot for a while the mucus builds at the back of his nose and he struggles to breathe comfortably through the night. We're using saline nose drops and snufflebabes, but I took him back to the doctor today after he brought up some mucus with his milk for the first time on monday evening. The gp has prescribed antibiotics which i'm reluctant to give him - it's a 7 day course and on day 8 he will be due for his first immunisation. I didn't air my concerns with the gp (a locum, as my doctor is on leave) and I know I should have, but I just feel he isn't that bad to warrant antibiotics at his age (apart from the length of time he's been poorly). Of course I'm not a doctor, so I don't know if I'm doing the right thing or not. I've collected the prescription and it's in the fridge, I'm just reluctant to use it. Thoughts please?
