Well water should be tested on a regular basis for impurities such as bacteria and harmful minerals. If you are on a municipal water system, check with the supplier to see if your water is fluoridated. Fluoride in the proper amounts is very important to healthy tooth development. If there is not enough in your water, or if your child drinks bottled or filtered water she should receive a supplement. Your pediatrician can prescribe the correct dose.
Food allergies can cause a variety of symptoms.
Hives or other skin rashes, swelling of the lips or tongue, vomiting, diarrhea or respiratory symptoms such as wheezing or difficulty breathing are the most common reactions. There is no evidence that behavioral problems are related to food allergy or intolerance. The most serious type of allergic reaction, anaphylaxis, can result from a tiny amount of a food to which a person is highly sensitive. Anaphylaxis is a life threatening reaction which is sudden and severe. It can cause wheezing, hives, swelling of the throat, and shock.
