I am so upset. My baby girl is 3 weeks old today and, after 3 visits to lactation consultant, she recommended supplementing today. She was born at 8lb6oz, lost down to 7lb14oz, gained up to her birth weight at 2 weeks, but has only gained 2 oz in the last week, putting her at 8lb8oz at 3 weeks old. We did a weighted feed and she only gained 1.2 oz. She hasn't pooped in nearly 4 days and even has decreased pee. On top of that, I've never felt full breasts, empty breasts, or let down, so I have no cues from my own body that things are going well. LC recommended feeding her, then pumping, feeding whatever I've pumped, then feeding with formula to get to a total of 3 oz per feed, 8 times per day, plus whatever other feeds she wants on demand from the breast. I'm so sad to be giving my baby formula and I'm scared we won't ever recover from this...that this is just rhe beginning of the end of our BF relationship. I'm so worried about my crappy supply. Any supplementing success stories out there? I could use some encouragement!
