The first thing to be done to prevent the allergies is to study how it works. The immune system of the body is organized in such a way to produce antibodies in order to fight against the bacteria and viruses. If you have wound in your body the immune system send some chemicals to heal the injury that is the reason you are getting itching and swelling over that particular area. However, sometimes the body takes the harmless substances like egg as well as dust particles present in air as a harmful one and tries to get rid of it. If you get sneezing due to the inhalation of some thing, your nose get swelling, this is because the immune system had send chemicals to fight against the unwanted thing. 

Being an infant, babies could not say anything about what is disturbing her or from what she suffers or how they feel. So it is always difficult to find out the reason for the cause of allergies. There are some frequent questions that the parents ask the doctors. 

How to find whether the child has allergy for particular food?
Allergy may be cause just from not many weeks to that of first 2 months, it usually depends upon how the child react to the content of protein in the milk, mainly, children causes allergy to the milk of cow. Naturally, children undergo stomach pain and starts crying, get bad-tempered and also spit out after gets feeding. The child gets diarrhea, loose stools, plus blood in stool. These are the common symptoms found in the children. Some children suffer vomiting, skin complaints, or have difficulty in breathing if the case is severe. Some babies may get irritated after taking cow’s milk and it forms to be the only symbol to understand that the child suffers allergy for cow’s milk, in fact, if you give some more milk in order to soothe her, the situation becomes more worse than before. And if your doctor finds out the reason for the allergy he may recommend soy milk or hydrolyzed milk of cow. In these milk the proteins are got broken down and the baby could tolerate them. 

Do pet at home causes allergies?
Yes, if there are pets at home the children are likely to suffer asthma and allergies. Cats are more allergenic as they leave fur which is a dangerous one.

The important fact that the allergy specialist agree with is that the child who is completely breastfed for the initial three month develop eczema only in a very meager number, when evaluated with those who fed rarely. AAP, suggest that it is good to have whole breast feeding for every babies in the beginning six months. And if your child seems to develop allergies, you could stop the breast feeding and go for the hypoallergenic milk of cow. In the cow’s milk the proteins are got broken and it may not cause allergies. 

The next question arises about the age, at which the babies must be given solid food. At present the opinion is that the solid food may help the babies to enhance their immune system as well as their burning capacity, this may also help to prevent allergies. Normally, solid food could be started for babies from four months, but, if your infant seems to have the danger of allergies, stop it for six months. 

The next thing is that how you are going to treat the child having allergies. Some time the child who suffers allergies may take some food items which are not allowed for him and as a result the child may be suffering allergy. The parents of the kid who suffers harsh allergies must always keep in their hands the bag containing children’s antihistamine such as Benadryl, or the epinephrine home injector. Epinephrine helps a lot before the baby is taken to the critical room for some more treatment. You must also be trained with the toy epinephrine injector to learn how to react in the emergency situations. Other than the parents all the other persons at home who is having habitual contact with the child in the house must be aware of the place where the injector is kept and the method of using it in the emergency situation.

She can feel better if you clean the nose by allowing drops of saline into her nose and get it moisture, you could also take the mucus out by making use of nasal aspirator. The child could feel better and her nose could be kept moisturized if humidifier or vaporizer is kept in the bedroom, this may also help the child to get out the mucus easily. The doctors may also give the prescription suggesting antihistamine like Zyrtec or Claritin fluid medicines and it will get rid of the allergic indications.
 
Wheezing does not mean there is asthma, it is the sound produced due to the narrowing of millions of small airways found in lungs, and if you blow the narrowed part sound may be produced like from that of flute. Already babies have very small airways and if it gets narrowed down due to cold or infections, breathing becomes difficult and the child starts wheezing. This is common for children and it does not mean the baby is suffering asthma. Albuterol helps the muscles to get relaxed and enhances the breathing of the child. 

However, the child has all the possibility of getting asthma depending on the family history regarding allergies or when your child has the symptoms of food or some other allergies like hives or eczema. For some the problem of wheezing might have happened once and it may not happen after, but if it continues regularly then your child is probable to have asthma. Moreover, asthma forms to be a chronic disease of respiratory organs, in which the airways of the person may get swelled and get filled with mucus if it happens to face triggers like dust, animal dander, mold and cold viruses. When the swollen airways get spasm baby starts coughing and gets wheezing and finds difficult to breathe.
 
Eczema appears to be a rough, red, itchy rash on the cheeks of infant. It may also appear at the backside of the knees and also in the corner of the arm. This may be due to allergies for some food, but the perpetrator might not be identified.

The allergy research throughout the world is revolutionized by this hygiene hypothesis. Respiratory allergic levels are high in the well developed countries and this research will surely give a new way of treating allergy. 40% children of US are suffering from runny nose, sneezing, nasal congestion and itchy nose. Most of them are affected during fall and some allergic to mold spores, cockroach allergens, dust mites and animal dander are affected through out the year.

Allergy is common in countries like Australia and Britain rather than in Ethiopia and Indonesia. Studies showed that children attending child care from early childhood were fewer likely to allergic diseases like asthma.

The path way of immune system has two ways to defend the foreign invaders from invading the body. Th1 creates T cells and antibodies which destroy bacteria keeping the normal cells of the body intact The TH2 cells let certain antibodies loose which grounds allergic responses sometimes to undamaging allergens. During pregnancy Th1 is inactive so that the immune system of the fetus does not reject the mother. After delivery Th1 path strengthens due to exposure to bacteria. Since the parents are over protective the development of Th1 is less and Th2 more which leads to allergy in children according to the Hygiene Hypothesis. However it can not be pinpointed that bacteria are good and hence allowing the child to amuse in dirt is not good.

It will take many years to find a vaccine for allergy but child allergy can be treated with allergic reaction shots and drugs. Nasal swelling can be treated with steroid sprays like Nasonex and Flonase. For children of age 6 Nonsteroidal sprays like nasal crom can be effective.

Some antihistamines help to relieve runny noses, itching and sneezing. Decongestants give mild relief of nasal swelling. Some eye drops are helpful to get relief from itching and redness in eyes. Some allergens are injected to the children in slow pace to increase the allergic reaction and it is found to give significant relief for some. Since it is risky it should be taken with care.
