Breast feeding and milk production

My whole pregnancy I was so excited to breast feed due to having PCOS I was told I may not produce a lot of milk. My daughter was born with a very tight tongue tie and I had to bottle feed her because she couldn’t latch. We got her tongue tie clipped at 2 weeks old but by that time she was so used to the bottle and now just screams bloody murder when trying to breast feed. I’ve been exclusively pumping for her. My milk came in on day 5 after and I was only getting 2oz per boob a few days pass without any supplements and I’ve started getting 7oz per boob and 14 oz per pumping session. My lactation nurse told me I can pump every 4 hours so me I was producing so much. I really wish her latching worked out and maybe it’s not too late but on the bright side I have so much milk stored. What else can u do with breast milk? I’m running out of freezer space and I’ve been dumping my pumps since I have no space. I need to go grocery shopping lol
