Ai, kesian you! Pregnancy ke2 memang lain-lain, hormon betul-betul buat puting jadi sensitive dan kering. Normal je actually, ramai mums experience ini, especially kalau first time breastfeed tak lama, puting belum "trained" lagi.
Since nipple cream biasa you try tak berapa help, some mums swear by trying a different cream formula, ramai kata Mama's Choice Nipple Cream memang bagus sebab made specifically to be safe during pregnancy and breastfeeding, and it really works for the soreness and dryness. Worth a shot before baby come, so at least puting sudah sikit conditioned. In the meantime, keep it clean and dry between applications, and maybe try compress with warm water juga.
But honestly, since this is pregnancy ke2 and puting still acting up, worth checking in with your gynae or midwife, benda-benda like infection or hormonal imbalance boleh juga cause extra sensitivity, and they can rule that out and give you more targeted advice. Better safe than sorry before breastfeeding starts!
