Regardless of what kind of floor you have, please don't use bleach - in fact get the bleach out of your house. Your baby(s) are going to be crawling on it and bleach is one of the most toxic chemicals they can be exposed to. You should not be exposed to it especially when you're pregnant. Please look into ridding your home of toxic chemicals before one of those precious children gets badly burned or worse. The manufacturers don't tell you of their dangers or no one would buy their products, but the majority of children's poisonings are caused from household cleaners, many that you would never suspect are very toxic. They are also very hard on your septic system. Many laundry products turn into a hard lump which will even clog up your pipes before they get into the septic system.

When I read some of the questions here I often wonder what a difference getting the toxic cleaning products out of the home would make.
