Aw mamsh, ganyan talaga pag may baby na lang-tulog sa isang side, lalo na kung mahabang breastfeeding period! A few of us moms went through this din, one friend's left side was super laki after exclusive feeding doon for months, pero eventually lumaki ulit ang right when she got pregnant with second baby kaya nagpantay na. Pero honestly, check with your OB kasi importante malaman kung may inflammation pa or kung babalik talaga sa normal once you stop breastfeeding, kasi every body is different. In the meantime, don't feel bad about it, marami sa atin ang dumaan dito at hindi lang ikaw!
