Apologies if this is a stupid question but its been puzzling me for a few weeks. We have started weaning dd and are introducing allergens. So far we have given cows milk, peanut butter and eggs. The health visitor said once we start on allergens we need to continue giving them regularly and ideally once a week. Does she mean one allergen per week or all of them? Im just thinking that the list of allergens is quite long and im going to struggle to give them all every week without going out of my way?
