Allergy Proofing

At 2 1/2 years old, we have discovered Noah is allergic to eggs and peanuts/tree nuts, mountian cedar, bermuda grass, and dust mites. This has prompted me to clean clean clean more often and allergy proof the house. Bought mattress and pillow encasements, allergy laundry detergent to kill those suckers, and vow to vacuum and wash the bedsheets every 2 weeks instead of every month or 2. I pray that this will help little Noah's allergic asthma and hope the new baby won't be so allergic.
