Twilite, in reading your posts, I see you are very concerned about potentially harming your pregnancy with chemicals. If you are at all disturbed by using the Purell during your pregnancy, don't use it. Use antibacterial soap, like dial or something.
As far as another post you had about cleaners and the potential for them to leech into your food, that is unlikely unless you dunk your food in cleanser. However, if using cleanser near your foods, use something 'natural' like baking soda and water mixed. It makes a gentle scrub. You can also use vinegar and water. The smell isn't too great, but it will not harm anything. Dish soap works great too!
Are you often disturbed with thoughts of poison chemicals harming you and the baby? Have you spoken to your doctor about this?
