For those that know me personally, they know I have an unhealthy awareness of germs. But to me, DIRT does NOT EQUAL germs. I love to have my kids play in the mud. I smile at dirty skin and mud on the face! However I will neither confirm nor deny that I hose them down with homemade hand cleanser after we leave a store, or if they touch elevator buttons. Why is dirt so beneficial? See for yourself this line of thinking: http://wellnessmama.com/12908/kids-need-dirt/.
