The Frequency and Duration of Breastfeeding Sessions

I am 10 weeks post partum. At the beginning, I was oversupplying and pumping every 2-3 hours getting at least 4-6oz out of each breast. Because of how much I was producing, I was told to cut down and start pumping every 3-4 hours instead. I did that and my supply DROPPED to 1-1.5 oz on left side and 2oz on right side. I take 3 different lactation supplements, post partum vitamin, tried power pumping, increase frequency and pump for longer times, etc. I'm only making 3.5ml per pump and my baby is eating/needing/wanting 4.5... She gets frustrated and fussy when breastfeeding (probably because she isn't getting enough), and no wonder because I'm not producing enough.. TIPS on how to increase supply?!!! I don't want to start using my stash..

3rd pump of the day 😮‍💨 using my speCtra. 💓 my volume definitely decreases the more frequent pumping sessions I have. What’s your secret to increasing your 🥛 volume? #spectra #pump #mothersmilk #breastfeeding

Any one else deliver premature, and have trouble breastfeeding? I had my son at 34weeks and this was after one or two pumping sessions He's currently in NICU so I haven't really been able to get him to latch onto my boob or have much skin to skin contact. I feel like nothing in this pregnancy went how I had hoped and now I can't even give breast milk? 😕 It got liitk bit yesterday I got 6ml I filled up 2 ot these syringes...but that was after 5 pump sessions. I have tea, a chocolate mix and 3 bottles if herbal supplements that I've been using. Has antibes gone through this and managed to start a mill supply once their baby is home.. or am I just a. Mom that will have to rely soley on formula?
