Hi, my DS is only three weeks old but has been given antibiotics by the doc for a cold. His breathing is very noisy - esp at night, and it sounds like he is very 'phlegmy'. He's also sneezing during the day. I'm not sure about giving him the antibiotics becasue I don't want him to build up a resistance to them at such an early age. Am I being silly? Should I just give him the antibiotics? Have to admit that I have already given him one dose as he sounded so stuffed up.
