I've never been told not to burn candles! I usually have them lit in my kitchen almost daily. My daughter is pretty good about letting me know if something bothers her and she's never said anything about my candles. I will have to mention it to her and her cf docs.
Also, we go camping in the summer and her favorite part of the day is sitting around the campfire at night. That hasn't seemed to bother her either. I will ask her docs about this also.
I tell you, I am constantly learning!
