Pregnancy, Breast-Feeding And Allergies
There is no evidence that avoiding foods in the diet of the mother during pregnancy has any effect on preventing allergic diseases in the baby.
2. For families with allergies, the mother should breast-feed for at least four months. This has been shown to reduce eczema and milk allergy in the child. It has also been shown to reduce asthma in the child for the first three years of life, but not after that.
3. There is no evidence that soy formulas prevent allergies.
4. Solid foods should not be introduced until at least 4-6 months.
