Shallow latch

Samantha
Have beenn dealing with a shallow latch since birth, have low milk supply because of it, or am assuming since no other reason found so far. My daughter is almost 6 weeks and we have to supplement with EBM and formula due to the limitations of how much she can get with her latch, just wondering if anyone else in the same boat and tips on what you did to improve the latch. Am regularly visiting with LC and trying everything they give me to do but doesn't seem to be any better. Would really love to keep breastfeeding but or schedule to keep me in any supply is tough so if things don't improve soon I think I'll have to give it away. Unfirtunately no luck with nipple sheild as my nipple gets pulled through the end so hurts more than her latch. Any advice greatly appreciated.
