We have used airborne before but I really just try to stock my kids up with fruits and veggies ( have more luck with the fruits) and they wash their hands a LOT. My mom is also a nurse and we always have purell. In the car, in my purse, in their backpacks. If they dont have access at a certain moment to soap and water we all use that.... sickness is really really over the top though in our area at the moment and we 4 of us 6 are sick. So no matter what you can only take so many precautions. Just keep your immune system healthy imho. :)
