That means stuffed animals, carpets, draperies (you want natural cloth that is untreated),
and make sure that there is no mildew on
the pillows or mattress. Mold
and mildew in
the walls may be problematic as well. If you can improve the air quality and give her immune support at the same time, you will really make some progress. (Remember exhaled waste is accumulative, so leaving a window cracked may also be helpful)
Many blessings.
