The one area where we haven't had to make any changes is cleaning the house. Several years ago, worried about what nasties there may be in cleaning products, I began to clean with bicarb and vinegar. I noticed no difference in the quality of the cleaning the house was getting so I've been using it ever since.
The children know when I've cleaned the house because they get home from school, take a deep breath and smell the vinegar. Not that pleasant but it doesn't linger long. Recently, I read that lavender oil was a good anti-bacterial and antiseptic so I mixed up a batch of water and lavender oil in a spray bottle. I used that today instead of wiping the bicarb/vinegar with a plain damp cloth. I also used it on the floors. As a result, the house smells very fresh.
