It'll just dry out eventually if you're not pumping or stimulating your breast no milk will come out. Warm water helps for the swelling and pain. But I do highly recommend breastfeeding it's so much better for your baby. I only did one month and then did formula and my baby ended up in the hoapital 7 days, he had constipation and a lot of diarreah his tummy couldn't digest the milk, too delicate. Not saying it will happen to u, but consider doing it for at least 3 months
Express enough in the shower to soften them and relieve the pain. You don't want to get mastitis! Put cold cabbage leaves in your bra too. That'll help dry them up.
