Almost forgot. There are special vacuums for allergy problems also. Get as many room air cleaners as you can and get them bigger than you need if you can put them through out the house it would be best. Put a wood or lino floor in the bedroom where she sleeps. I know it sounds like a lot, just do a little at a time. Been there, done it all and even more. Stay strong, get as much info as you can, try mothers of asthematics to start. You can do this after awhile it becomes normal, at least to us. Good Luck to you Marilyn
