Hey mama! Yan ay normal lang, usually yan ay dried skin or colostrum na nag-harden, lalo na kapag malapit nang mag-deliver. A few of us din experienced na ganyan before labor, kaya don't worry too much. Pero since you're almost at term na, better check with your OB just to be sure everything's okay with your nipples and milk ducts, especially para ready ka na pang-breastfeed after birth. In the meantime, try Mama's Choice Nipple Cream, it's pregnancy-safe and breastfeeding-safe, and sobrang helpful talaga para sa nipple prep ngayon at pang-comfort lang habang naghihintay.
