Re: Shallow latch: lip or tongue tie?
Wow, that first pic is a great one! I definitely see a small but noticeable heart-shape divot on the top of her tongue. I think I would take her to the ENT, and see if the tongue can be released. If you are no longer in pain and baby can stick her tongue out past her gums, I am not sure that this absolutely needs to be treated... But I also think it's worth seeing the doc about it.
I imagine you are DONE with the pump and the Domperidone... What do you think would happen if you slowly cut both of those things out of your life, and just let baby nurse while watching diaper output carefully? I mean, if you're not in pain when she nurses her latch must be pretty good, and a painless latch tends to be an effective latch. Perhaps if you allow the oversupply to slowly taper off, your baby will gradually increase her feeding effectiveness and by the time supply is more or less equal to demand, she'll be able to maintain it without you needing to work so hard.
