Ay anak, better check with your OB talaga about this one kasi may health reasons kung bakit you're asking, baka may concerns ka with breastfeeding or something else going on? Three months postpartum ay okay pa rin for breastfeeding if gusto mo, pero if may medical reason why you want to stop or if something's uncomfortable, your doctor can give you proper advice on how to do it safely para hindi masyadong masakit or may complications. A few of my mum friends had to adjust their breastfeeding plans for different reasons at that stage, at ang doctor talaga ang best magsabi ng safest way para sa situation mo.
