My LO is 11 weeks old, and I've been struggling with low supply since day one. I have finally felt like I could skip the supplementation for the last 2 days, as DS has had several wet diapers each day (but still waiting for a poopy diaper since I stopped the formula). When I was supplementing him, the purpose of his nursing didn't matter as much because I wasn't worried about him going hungry. But now that I am not supplementing him, I'm concerned that he's still hungry. DS is sucking his hands and fingers a LOT, especially in the early afternoon through the evening. Occasionally this escalates to crying, but I try to pick him up before that. He'll suck his hands and fingers even right after I've fed him, which is why I'm concerned. Could this be anything besides a hunger cue? Or is my LO just still hungry?
