My 9 week old son seems to have a cold - he's sneezing, has difficulty swallowing and is quite snuffly. He's been a bit scratchy all afternoon, but is asleep now. Should I give him some Calpol when he wakes up for his next feed? I don't want to over-react, but I don't want him to be in too much discomfort, either. Every time he sounds as if he's choking, I have a little panic attack. Any suggestions?
