I've just read something that said that there are a number of foods/drinks which you should not eat when you are breastfeeding because it will likely cause your baby to be irritable or colicky. On the list: chocolate, coffee, garlic, spicy foods, all dairy products- especially milk, citrus fruits and juices. These are all the foods that I love to eat. Do I really need to follow this advice? Can someone please comment? TIA
