My son is 4 months old, and I exclusively pump. I tried nursing for weeks after he was born and he would just scream (NICU gave him FAST FLOW nipples even though they knew I wanted to bf), and it was so frustrating. But every time I take him to the pediatrician, she asks what kind of formula he's on. I say he's not on formula, and she asks how often he's latching on. EVERY SINGLE TIME, I have to tell her that he never latched on, that I have to pump and bottle feed. It still upsets me that I can't breastfeed, and every time he's at the pediatrician, it gets brought up. His chart says that he's bottlefed breastmilk, so I don't know WHY she continues to ask over and over again. It almost puts me in tears every time.
