My son is 6.5 months old and has been BF with bottled BM supplement since birth. He started some solids at 5 months and loves them. We have struggled from day 1 with BF, having to use a shield until he was 4 months old and struggling to maintain supply that whole time. I am currently on domperidone (40 mg/day) and I pump every evening to help with supply. For the last couple weeks, he has been acting very frustrated while BF. He pulls off, grunts and screams, arches his back, and then relatches. He does this sometimes outside of BF when he wants to be put down or something, so I might think it's just him telling me he's done except that he gets back on after a second, which makes me wonder if he is not getting enough milk. Certainly I don't feel as strong a letdown as I had before, and I'm not engorged like before either. I know that's normal with an older baby but in combination with his behavior it's making me very concerned that he's not getting enough from me. Should I up my domperidone dosage? Pump more often? Or is there another possible cause for his weird behavior? He is currently peeing lots (8+ wets) and pooping plenty (4 medium sized poops today!).
