Some children are sensitive to some substances which can be harmful. Some of the substances are fungus, molds, pollen, dust, smoke, animal hair, some cosmetics, synthetic fabrics, hair dyes, some medicines, and some foods like milk, nuts, chocolate, fish, egg and so on.
There are number of allergy manifestations. The common type being the child who forever has a running nose or catches a cold very frequently. Hay fever is another type in which the child starts sneezing suddenly and his nose and eyes start streaming. Skin allergies may develop rashes and urticaria (hives), which are raised reddish areas.
Stings of bees and wasps produce severer reactions of allergy in children. Eczema is also an allergic skin disorder. There are also allergies of the lung passages and the lungs, resulting in allergic bronchitis and asthma (wheezing chest).
It is good to seek the doctor’s advice as there is no immediate cure for allergy. So you will have to be patient to deal with the problem, helping your child to do so too. It may be very difficult to identify the offending allergen and then avoid it. Children who have hay fever or asthma should use a foam mattress and pillow. It is best not to have carpets or upholstered chairs in the room, so that it is as dust-free as possible. Stuffed toys and animals should be avoided. Sometimes a pet may have to be given away if your child is wheezing or sneezing is found to be associated in any way with playing with the dog.
