Many parents are concerned about food allergies in their children. About 4 out of 100 children have a food allergy. For most children with a food allergy, the best thing to do is avoid the food that causes the allergic reaction.
When a person has a food allergy, the body overreacts as if the food were harmful. The body fights the substance in the food that triggers the allergic reaction.
A person can be allergic to any food. Although some people are allergic to food additives (such as food dye and artificial sweeteners), natural foods cause the most food allergies. Almost all food allergies in children are caused by these foods:
Sometimes a child is allergic to more than one food.
Here are common signs of an allergic reaction to food:
Skin reactions are the most common signs of a food allergy. Sometimes people with food allergies develop long-term health problems. The most common asthma and eczema (itchy, scaly red skin).
Avoiding the food that causes the problem
If your child has a food allergy, she should avoid the food. Read food labels carefully. For instance, some foods that you don't expect contain peanuts or peanut oil. The label will tell you. At restaurants and at other people’s homes, ask if the dishes contain the food your child is allergic to.
When children have food allergies, health care providers may recommend that they take certain medicines. Examples include inhalers and liquids or pills called "antihistamines."
Anaphylaxis is a serious allergic reaction. It can occur if a person has a severe food allergy.
Anaphylaxis comes on quickly and can be life threatening. The person has a hard time breathing. Her blood pressure may drop quickly, causing her to faint or go into shock. The person must be treated quickly.
Before anaphylaxis can occur, the person must have eaten the food that causes an allergic reaction at least once before. In other words, a child allergic to peanuts will not have anaphylaxis the first time he eats peanuts. But sometimes it's hard to know if a child has already eaten the food.
If your child has a severe food allergy, his health care provider may give you special "pens." If your child has an anaphylactic reaction, you can use a pen to quickly give him medicine. Baby sitters, child care workers, family members and others who spend a lot of time with your child will also need to know how to use the pens.
Children usually outgrow allergies to cow's milk, eggs, soy and wheat. But they do not usually outgrow allergies to peanuts, tree nuts, fish and shellfish.
Medical research on prevention of food allergies is limited and incomplete. After reviewing a wide range of medical research, the American Academy of Pediatrics has made these recommendations about food allergies in children:
Medical research about food allergies is continuing. If you have any questions about food and your baby, ask your child's health care provider.

Vitamin D is important to help avoid a bone-weakening disease called rickets. All babies should receive 400 IU of vitamin D per day, starting in the first few days of life. This includes breastfed babies and babies who drink less than 1L of infant formula per day.
Our skin makes vitamin D when it gets sunlight. But too much sunlight can be harmful, too. In fact, babies 6 months and older and young kids should stay away from direct sunlight and wear sunscreen at all times when out in the sun. However, sunscreen stops the skin from making vitamin D. The best way to get enough vitamin D is by giving your baby liquid multivitamin drops with vitamin D. They can be found in many pharmacies, and you won't need a prescription for it. Just be sure you've filled the dropper to no more than 400 international units (IU).
All babies are different and have different feeding patterns. In general, breastfed newborns need to eat 8 to 12 times in 24 hours (about once every 2 to 3 hours), for about 30 minutes each time. Breast milk is easily digested so it may be difficult to time when you should nurse your baby.
Newborns may need to feed more frequently than older babies. They may need to be fed on demand. As your milk supply is established and the baby grows, the baby's feeding patterns may change and she may go longer between feedings. Remember, breastfeeding is a natural skill, but it’s also a learned skilled. Be patient and give yourself (and your baby) time to master this new ability.
Begin with a single-grain iron-fortified cereal such as rice, barley or oatmeal. Mix it with breast milk or infant formula. Start with a small amount once a day. It's hard to tell how much your baby will eat. At first, most of her food will probably end on her bib or face. Be patient and help your baby learn this new skill. It's important that meal time is a pleasant time. This will build the foundation of healthy eating habits. If your baby cries, shows no interest in feeding or turns her head away from the spoon, stop feeding her. She is trying to tell you that she's full or she doesn’t want anymore. You should never force her to eat more than what she wants.
Breast milk is the best food for most babies. It's best to give only breast milk for the first 6 months of life. Some babies might be ready to start solid foods between 4 to 6 months of age. When your baby is between 4 to 6 months, she may begin to show signs that she's ready to try some solid foods alongside her breast milk or formula. Watch for her developmental cues (signs) and she'll let you know when she's ready. Some signs that show your baby might be ready to start solid foods are:
