I need advice... I have a seizure disorder so I take meds for it I also take antidepressants for major depressive disorder and borderline personality disorder, I called the pediatrician I want her to see when she's here....and he told me after I've been told my two nurses I can breast feed when she's born that I can't breastfeed. I'm so upset emotional wise I wanna breastfeed her... does any of mommies have advice? I'm 26 weeks today...
