A week pp, still no milk 😖

JMR
Getting so bummed out, we've had to supplement with formula since day 3 because she was losing too much weight, and now she's having latch issues. I pump every 2-3 hours so I'm able to feed her colostrum, but I can't believe my milk still hasn't come in. It's been hard not feeling like I'm failing her. I had this grandiose thought that BF would come naturally to both of us, but that hasn't been the case. Any support is appreciated.
