What can I do to keep a cough at bay with my 3m old? I took her to the doctor today he said everything was fine, her ears are clear, nose mucus was white and lungs were clear though he did see a little bit of drainage in her throat I'm already giving her saline drops in her nose every couple hours but what can I do to keep the cough from progressing? I have a lung infection and just want to make sure she doesn't get a worst cough with out drowning her in saline.
