Supply Tanked! 😭

So, my baby was a NICU baby and the first time he was able to eat, he was 5 days old (prior to that, he was being given supplements in an IV nutrition line). He was bottle fed until he was 10 days old and then we found out he had a pretty significant posterior tongue tie that had to be reversed. Because of its severity, he had to be taught how to use his tongue the right way... easier said than done. When he nursed he got so frustrated because his tongue was messing up and he couldn’t get much out. I had to end up bottle feeding him pumped milk. Since I had so much in the freezer, I slacked on my pumping. Mistake! I can only get like 1-2 ouncescombined from both boobs combined. Any thoughts on how to pump me back up? I have lactation cookie mix and stuff, I just need some help on things I can actually DO not just eat or drink certain things. I was able to feed my first until she was 8 months old, but she could latch well. This baby doesn’t. 😕 He’s only 10 weeks old, I want to AT LEAST make it to 6 months. 🎉
