just starting.. please help!

💔
For whatever reason my daughter (born 3/20/17) is refusing to latch. I met with lactation consultants 4 times in the hospital and still plan to! In the meantime I'm pumping and we are supplementing, but I have a few questions! 
1) my like isn't in yet. So I'm only getting a little bit of colostrum, although tonight it seems to be thinning out so I think my milk is coming.. that being said I only got 10ml in a 30 minute pumping session, BUT st least 7ml came from my right boob. My left boob isn't producing and for whatever reason when I'm trying to latch my daughter she screams on my left??
2) best way to be storing these small amounts/ heating them up/ serving them? We are supplementing so many times I'm pumping while my husband feeds and so she is not ready for mine yet.
3) ANY other tips would be greatly appreciated!!
