I took DD to see doctor on Monday, as she had a really bad cough. I wanted to check that it was just a cough. The doctor prescribed antibiotics and I said that I didn't want to give them to her. The doctor said to use my common sense and if it hadn't cleared in a couple of days to give it to her. The cough has now changed and I can feel the 'bubbling' as she breaths when I hold her. I am not sure if it has now become a chest infection rather than just a cough. I am SO reluctant to give antibiotics to a 3 week old, but I feel that I may have to give in now, as she has been ill for over a week. I'd appreciate any opinions on this one...
