Aw momshie, ganyan talaga ang dami namin na nakaexperience yan, usually yung dominant breast ang mas abundant, kaya asymmetrical production is pretty common! Ang good news, pwedeng mag-improve pa, lalo na kung consistently mo siyang ibreast-feed, pero honestly three months in yan na usually ang pattern na establish na ng body mo. Better to chat with your OB or lactation consultant about it kasi they can check kung may underlying issue like blocked duct or positioning problem na pwedeng i-address, tapos they'll also give you realistic expectations kung babalik to normal or hindi, some of us moms lang talaga end up with one dominant side and that's okay din! For the soreness or any discomfort, I swear by Mama's Choice Nipple Cream, it's safe while breastfeeding and sobrang ginhawa. Fingers crossed for you, momshie!
