not much you can do, just hold out and in a few years (like 5 ) the sickness will subside! hate to be the bearer of bad news but in order to keep "sickfree" IMO you need to build your immunity and in order to build your immunity?... you need to come in contact with all that crap! It stinks, but good news is, once you have a great immunity you and your family will barely ever get sick. My first few years especially it seemed if I wasn't sick one of my kids were or another day care kiddo would come in with a whole new set of germs to spread. you can do all of the above, lysol, clorox, wash, wipe and steam, but the biggest problem is the lower immunity, little people have low immunities and so do most who haven't been if full contact with all the germs in this nasty world. Good luck, find some good meds, take your vitamins and pray for spring!
