Post-pregnancy snacks should prioritize nutrient-rich foods and drinks that support breastfeeding mothers. Essential foods include lactation cookies, fruits, yogurt, smoothies, hard-boiled eggs, and cottage cheese. Hydration is crucial, with adequate water and milk intake. Supplements may be needed to ensure essential nutrients like iron, calcium, vitamin D, and omega-3s. Breastfeeding accessories like pillows, bras, nipple cream, breast pumps, and milk storage bags enhance comfort and convenience during this nourishing journey.
