Dr. Shaw, I fully respect your med reference that you used to recommend against the use of tea tree oil on nipples. Would you like to address all the products containing tea tree oil such as toothpaste, dental floss, and throat lozenges that I happen to use that have the tea tree oil as the main ingredient? Did the reference say that the symptoms were specific to infants/toddlers and not adults? I gues my main concern is for my toddler & small children. Also, the products are coming with no warning against infants using the products. Thanks for your input. Lora Gleaton, LLLL
