4. Keep a clean home. There's no need for mold, dust, or ill-kept food items. Keep the fridge clean and put a date on your leftovers using a label or masking tape. You might also try hepa filter-based vacuum cleaner bags and ac filters.
5. If you have a furnace, get it professionally cleaned and checked annually, especially if your furnace burns propane, butane or oil. These are possible sources of carbon monoxide from which you'll want to protect your family.
6. Find out all you can about bisphenol A. According to Scientific American (12/16/07, Fighting Toxins in the Home by Mark Alpert), bisphenol A may be a "component of the light plastics used in baby bottles and many other consumer products." It can "leach from the plastic lining of canned foods," according to Wikipedia, and can get into infants who are "fed canned formula with polycarbonate bottles." Accordingly, many physicians are recommending that pregnant women not drink from plastic bottles.
7. Keep those phenols out of the house, and away from your body. These carcinogens can be found in some disinfectants, perfumes, glues and air fresheners. The best way to freshen the air in your house is to open the window. If weather is an issue, consider installing a fan-based ventilation system. Don't spray things willy nilly into your home's air, like they do on television commercials.
