As babies grow and develop, breast milk or formula alone can no longer meet their nutritional needs. The World Health Organization recommends that babies be given complementary foods from 6 months of age. But in the process of adding complementary foods some babies will appear allergic phenomenon, so the baby complementary food allergy how to do? How to deal with it? To the baby to add the principle of complementary foods 1, to the baby to add complementary foods time should not be too early The baby due to the digestive system is not fully developed, too early to the baby to add complementary foods, not only did not play a role in adding nutrition to the baby in a timely manner, but also may trigger the baby’s allergies, so to the baby to add complementary foods time to choose the best in 6 months or so. 2, baby supplemental food selection should be careful Easy to cause allergies in small children’s food roughly: milk, eggs, soy, peanuts, fish and shrimp. If there are these kinds of food in the baby’s complementary food, then mothers and fathers should be careful, especially if both parents or one of the parents will be allergic to a certain kind of food, then pay more attention to whether the baby will also be allergic. 3, supplemental food 4-7 days for a stage to the baby to add supplemental food, do not “quick success”. Every time you add a new complementary food to your baby, the period should be about 4-7 days before you can. This not only allows your baby to gradually accept new foods, but also allows you to learn which foods cause allergies in a timely manner. Baby allergy symptoms usually do not wait too long to show. 4, which food is easy to cause baby allergies Dairy products Dairy products are one of the most likely to cause baby allergies, so it is recommended that the mother as far as possible breastfeeding. Egg food Baby due to the development of the mucosal barrier of the digestive tract is not complete, the egg white protein molecules in the egg is very small, very easy to enter the bloodstream through the mucosa of the intestinal wall, causing the baby’s allergic reaction. Therefore, it is recommended that egg yolks be added to babies at seven months and egg whites be added after one year of age. Seafood Fish, shrimp, crab, sea shells and other foods are also prone to cause allergic reactions in babies. When should I suspect food allergy? Itchy skin: red spots or rashes of varying sizes appear on the skin (mostly on the skin of the face, neck and ears), some may appear as bumps similar to mosquito bites, some show dry, flushed skin, or may be a worsening of the baby’s pre-existing eczema symptoms. Gastrointestinal reactions: nausea, vomiting (e.g., frequent spitting up), abdominal pain (crying and restlessness), constipation, diarrhea, and loose watery stools. Mouth and eyes: redness and swelling of the mouth and lips, ulceration of the tongue, babies may cry and refuse to eat, some babies may show rubbing of the eyes, tearing of the eyes, congestion of the eyes and redness of the surrounding skin. Whistling manifestations: cold-like manifestations, always rubbing the nose (itchy nose), sneezing, running watery nose, may also cough (paroxysmal dry cough, more pronounced at night), shortness of breath, and even difficulty in whistling (must be immediately hospitalized). General: Some babies may cry more easily, seem to have no energy, seem to sleep all the time, and older children may complain of headaches or show a variety of emotional problems; in the long term, they may also show no weight gain or even weight loss, and slow height growth. If any of the above conditions are present, and excluding other factors such as colds and changes in the family environment, it is important to be careful of allergies in babies, especially in those with a family history of allergies. What should I do if my baby has a food allergy? Avoid the allergic food: First of all, stop consuming the allergic food and the related food containing the allergic food formula immediately. However, children with mild allergies should be reassessed periodically to see if they need to continue to avoid the food. Symptomatic treatment: Once a specialist has confirmed that your baby has developed a food allergy, symptomatic treatment will be given according to the severity of the symptoms and the degree of physical damage. Food substitution: If the baby is allergic to cow’s milk, he/she should continue breastfeeding or be replaced with a deeply hydrolyzed protein formula or amino acid formula as appropriate; soy protein or goat’s milk formulas are not recommended because 30% to 40% of babies may be cross-allergic. Warm tips: Parents should not rely solely on the results of the allergen test to conclude that the baby’s food is allergic or not allergic, and then strictly prohibit the baby from eating the food, which will have an impact on the baby’s growth and development. Generally speaking, negative or positive allergen test results are for reference only and should be referred to a specialist for comprehensive judgment. Once a baby has an allergic reaction to a certain food, is it necessary to stop adding this kind of food? Since babies’ intestines and digestive systems are not fully developed when complementary foods are added to their diets, mothers and fathers can refrain from giving their babies these allergens in the near future, but can wait until their babies are one year old or older before trying them again. Usually, as babies grow slowly, they will no longer be allergic to the foods they were once allergic to. But if mom and dad have some specific allergens, then be careful. In addition, a strong body will help your baby fight off incoming allergies, and the best way to ensure that your baby’s body is strong is through a nutritious and balanced diet. For allergy-prone babies, moms should pay more attention to the nutritional balance in their babies’ daily diets, so that babies can consume more and more balanced nutrients from food and grow healthily.
