My son is 16 weeks and I've had to stop nursing. I am devastated. This is my last pregnancy and I was hoping to nurse until like forever.. lol. But that's not in my stars. He's a boy, he's always hungry, I never made enough to begin with and I have to go back on my seizure meds. Is there anyone out there struggling with nursing issues??
