Please Help! Over Supply/Engorgement

I’m really desperate for some advice regarding an over supply issue and engorgement. Baby is six days old and I’m already running into pain from being so full and we’re running into issues with him feeding because I am producing so much milk. Things like him eating too fast, struggling to latch and relaxing, because my breasts are so full, and other digestion issues are really affecting our feedings. Please let me know your tips and tricks to help with your oversupply and engorgement.

I am mostly trying to use just a hakaa seldomly, so I don’t create more of a supply issue and icing after each session. And trying to have more frequent feedings in between.
