I would give your Dr. a call even if it is just for piece of mind. A lot of paints and stains actually let of toxins into the air for up to a year. I don't think they have such a thing as toxin free stain, however if you have to paint anything, i.e. nursery etc, I would suggest a paint with no VOC's. That is what we used it is a little more expensive but worth the piece of mind! You can get it at Home Depot.
