like Biggie, my focus is on cleaning babies hands often since my LO sucked her finger alot and to make sure hands were washed before meals. didn't use anything specific to clean floors - well, diluted bleach to mop a couple times a week and vacuum also a couple times a week. we have a dog (small one) but when our baby was small they were never in the same area at the same time. think being too clean is more harmful to the baby - not that i want my kid to grow up in a dirty environment, but some dirt is good for kids
