As a Dad, my wife and I of course want the best start for our toddler (aged 3) - however, I am concerned that my wife is excessively worried over our son's diet and stops him from eating all sorts of food, in case eczema occurs (he did have bad eczema as a baby). I wonder if other parents have the same worries too ? - foods that are banned include: milk (we use special non dairy), white of eggs, fishcakes, fish fingers, chocolate, ice cream, cheese, honey. I have tried to introduce (secretly some of these foods, and can see no ill affect) - Is there a proper allergy test that can be taken, and f so how often should a child be tested.
