Hmmm...nowhere did I say kids shouldn't be exposed to dirt. Mine were and they're as healthy as horses...cept the ones with horse flu. They're not doing so well. I digress though.
Kids should get outside and do all that stuff kids do including stepping in dog shit etc. I don't agree with the trend these days to keep kids 'clean' all the time. I disagree with those antibacterial hand soap things you can get these days. I think too many mothers stop their kids from exploring their environment for fear of 'germs'.
That being said, I stand by my reasons for keeping a clean house.
Outside is where kids should be exposed to dirt. Not inside.
