Is avoiding foods that are likely to give my kid an allergic reaction as early as she’s a baby will guarantee her that she won’t be allergic to them when she gets old?

According to this article (http://www.fitpregnancy.com/pregnancy/pregnancy-health/allergy-avoidance), it seems like withholding allergenic foods may actually increase your baby’s risk of developing food allergies. A study conducted in 2008 found that there is a higher chance of developing peanut allergy in children who did not consume food that contains peanuts during infancy or early childhood, as compared to those who did. It may be good to gradually introduce allergenic food into your baby's diet while you are still breastfeeding. At the same time, keep a lookout for any allergic reaction (such as hives, itchy eyes or mouth, vomiting, pale skin, fainting, difficulty breathing and swelling of the eyes, tongue or lips).

Children who are at high risk of developing allergies, like those whose parents or siblings have allergies might benefit from being introduced to solid foods known to cause allergies, at a later period. It's best to offer least-allergenic foods, such as rice cereal and root vegetables, first. When you introduce grains, save wheat for last, as it's the most allergy causing grain. While egg yolks are okay to try, egg whites are a source of the allergenic protein, albumin, and should be reserved until your baby's a year old, has been exposed to more solids and his immune system is more developed.

To add on to the ladies, if your family has a history of family member that is allergy for example, nuts, it's also best to delay it after they are 12 months and above and start small. Also, there are allergy tests that you can do if you think that your baby is allergic to a certain food. For more information, you can check with KK Hospital. I believe Singapore General Hosp has the same test too but personally I would go with KK Hospital since they specialize with kids. http://www.kkh.com.sg/Services/Children/AllergyService/Pages/Home.aspx
