Remove dust collectors from the child's room so their body can rest overnight. They are then able to tolerate more during the day. Removing stuffed animals, avoiding clutter and using washable rugs are some suggestions for dealing with dust and dust mite allergies. Animal allergies are usually associated with the animal's dander. Try to keep the animal outside as much as possible and out of your child's bedroom.
Pollen counts are usually highest in the morning and lowest during wet weather.
Avoid planting trees or shrubs near the house and minimize contact with flowers, both indoors and outside. Avoid dampness and high humidity in your home, as they are associated with molds. The changes that are needed are all dependent on the severity of the child's allergies. It's important to try to make changes without making the child feel that they are being isolated or deprived. If objects need to be removed, try to replace them with other more suitable yet pleasing objects.
