I am around 16 kindergarteners everyday. Imagine the running noses and coughs I encounter. I am 14 weeks pregnant and am trying to prevent becoming sick. I know there is something you can take to help prevent getting sick. I think one brand is called airborne. It is something to boost your immune system. Has anyone tried anything like this? Or does anyone know of a brand I can check out? I wanted to get more information about it before I ask my doctor if it is safe to take. Or does anyone know another safe method to help prevent me from catching all the little germs the kids bring into the classroom?
