Please tell me what food to avoid during breastfeeding?

A varied list: Some people can eat everything, some can't. So you can cheat some with this list... 1. Cabbage 2. Onions and garlic 3. Spicy foods 4. Cruciferous vegetables (broccoli and cauliflower), radishes, asparagus 5. Caffeine 6. Dairy and tomatoes you may find some of these foods are well tolerated, and you can eat lots, and find some foods you didn't know about (almonds, carrots). Comes with experience.
