You should continue eating what you enjoy! If that means spicy dishes, go for it! I don't know what I'd do without my kimchi! In fact, it will be beneficial since your baby will be exposed to those flavors that frequently grace your table from early on through breast milk. This can help them to accept those foods later on in life. Of course if your baby shows any kind of reaction, fussiness, or intolerance, then avoid that food.
