Fenugreek does not work for everyone, some may find that fenugreek decreases their supply drastically. Do you pump? (Since you mentioned baby don’t seem to take direct latch well)
Our milk works on demand and supply, if you don’t remove the milk diligently, you’re signalling your body that you don’t need supply. So if direct latch does not work for you, try pumping even when baby is on formula.
If you made up your mind that you want to provide bm, you have to pump diligently or latch (can engage LC to correct the latch). If your milk is too thick, try sunflower lecithin to thin out the milk.
Don’t need to feel sad. Slowly build up and you’ll eventually get there. Don’t stress, just remember regardless of whatever milk is it, as long as baby is fed well, it’s good milk. Stress is a milk killer. I also mix feed baby back then while I build up my supply as well.
Goodluck! 😊
