First of all, it is necessary to find out which product causes an exacerbation of the disease in the child. This is done using blood tests and skin samples. In addition, the mother of such a baby must keep a child’s food diary in which she should enter all new products introduced into the child’s diet and his reaction to them. If any of the products provoked allergies, then it must be removed from the baby menu for at least 1-3 months. Further, in agreement with the doctor, this product can again be added to the children’s menu, but this should be done gradually, starting with small doses and, of course, observing the health of the child.
