How common are allergic reactions?

Allergic reactions are fairly common now because there is so much of write ups on this issue. Plus, as parents we are now better at detecting these reactions. The golden rule is to avoid certain foods during the weaning stage, and these include cow's milk, eggs, soya and tree nuts, gluten-rich foods especially wheat, shellfish, citrus fruits, chocolates and tomatoes and food additives. Prepare and introduce new foods, single ingredient on its own for 2-3 days at a stretch. Check for any reactions and likes and dislikes of your baby before moving on to the next food.
