You do your best all winter to not get a cold but when you have kids in school specially little ones its almost impossible. You feed them the good stuff vegetables etc. give them the vitamins and they still get sick. We wnet over to the schoolone day to pick up ourson early, looking into the classroom the girl next to our son sneezed directly on him. How are you going to protect him from that? So he got the cold brought it home to us and it could take up to ten days to clear our systems.
