I think its importent to remember that while being clean is a must, there is such a thing as too clean. Children who are not exposed to germs as infents and toddlers are sicker later in life because they just don't have that amunity built up. People where not ment to live in starile enviroments. In fact if you watch, the children who are the durtiest are often also the healthiest.
I'm not saying let your kid be a mess, or never clean their toys or bottle's and stuff, just try not to go over bored. All these drug resistent super bugs are crearted by the high increase in antibacterial products, and too clean enviroment.
