Hi ,my nine month baby has had a very runny nose for the last two days,I guess this could be because I have a strong cold at the moment and he has picked it up from me . I have given him calpol at night over two nights as I was concerned it would get worse,but I have just seen he has a rash on his lower back ,could this be a reaction to the calpol,should I take him to the GP to have a look? Thank you for your time and advice. Kind regards. Carmen contreras
