Ay sis, yan talaga ang common struggle! A few of us moms in our circle experienced that random soreness, sometimes okay lang, sometimes grabe, sometimes walang problema, and honestly it can be frustrating not knowing kung ano ang trigger. It could be latch, engorgement, or even just the sensitivity ng skin, kaya I'd really suggest checking with your OB or lactation consultant para ma-rule out kung may cracked nipples or inflammation, because they can give you the right solution based sa actual situation mo. In the meantime, a lot of moms swear by Mama's Choice Nipple Cream, it's pregnancy-safe and breastfeeding-safe, and it really helped ang amin with the soreness in between feeds. Try din na alternate positioning at make sure baby's latch is deep, pero ang best step talaga is professional advice para ma-address ang root cause! Kaya mo yan, mama!
