You don't need to avoid any foods! Old wives tales tell us that certain foods will make our babies gassy, but what we know scientifically is that that's just not true. A very small percentage of babies will have slight food intolerances based on the mother's diet, but more often than not, we really recommend moms eat everything in their diet. You should be eating a very nutrient-dense, rich array of foods. Spicy foods, cruciferous veggies, and other foods that were considered bad for lactation are really just myths.
