Ay, mama, na-experience din namin yan ng iba naming mom friends, ang cracked nipples or super sensitive talaga when breastfeeding, lalo na if newly postpartum ka pa lang! Since 4 months preggy ka pa, siguro ang breasts mo ay nag-aadapt pa lang sa whole breastfeeding thing, kaya the soreness and cracking, pero best to check with your OB or lactation consultant to make sure walang infection or latch issue, kasi sometimes it's just positioning lang. One of my mum friends swears by Mama's Choice Nipple Cream, which is pregnancy-safe and breastfeeding-safe, and she said it really helped her soreness mawala in a few days! Fingers crossed for you, mama!
