My 5-yr-old has had a cough that just doesn't want to go away for about a month now. She doesn't cough constantly, but when she does, it is one of those gross-sounding ones. Now my 11-yr-old seems to have it too. I have already tried to cut back on their dairy, but what else can help? I really don't want to put them on antibiotics! But enough is enough!

Could be something with her lungs or allergies. Have you seen a doctor that can examine her

There is a really bad coughing bug going around here at the moment too we had ours for about six weeks, its best if they do cough though to get rid of the congestion plenty of vit c, and maybe try the old vicks vapour rub on the soles of their feet when they go to bed at night it might help, put socks on as well.

No, she's not seen a dr. for this.
Have been giving her vitamin C, but Prob need to give more.
