Girls, can you tell me how you fed during breastfeeding, especially at the very beginning? What did you absolutely exclude besides chocolate and citrus fruits... I'm currently on porridge and soups, but I think it will be long like that. Recently, I ate some salad, so the baby started having terrible colic. I don't remember how I fed when I was breastfeeding older children, but I think I didn't restrict myself much.
