I've recently discovered a winning combination for a herbal tea blend. This blend can help with your quantity and quality of milk for your baby so it's great even if you haven't had any supply issues.
I mixed 2 table spoons each of fennel seed, caraway seed and fenugreek with 3-4 tablespoons of lemon verbena. Combine ingredients in an airtight container. Place a teaspoon in a cup with boiling water and brew for 5-10 minutes. Tastes great warm or cold.
