Talk about something happy. No matter what the child says or does, leave the room. If they start to complain or start to cry, tell them you'll be back to check on them in five minutes. Be calm, be firm and don't give in. By the end of a week, parents usually will see some amazing results.
Many children have allergies to pet, dust mites, pollen and molds.
Since small children crawl and play on the floor, that is where allergy control must begin. If possible, minimize the amount of carpet in living areas. Mats or small area rugs will help protect the floor and provide softness for walking and playing. Floor coverings placed at all outside door entries will collect dirt, dust, pollen and other allergens brought from outside and reduce the spreading of allergens to other home areas. Regularly shake rugs outdoors, away from windows.
