Breastmilk?

Anything else I can do to make my milk finally come in? My baby is 3 days old. He has high bilirubin so I am desperate to feed him as much breastmilk so he poops it out. Right now I am breasfeeding what I can give and supplementing with formula at the same time. I also pump after just to stimulate it. I am desperate. I am a FTM and I feel like a failure :( Any advice????
