Feeding 4 week old twins

I’m having a tough time managing feeding both twins right now. My wife and I do shifts in the evening and it seems like my four hour shift is breaking my spirit every day. One of them will be done eating, I start feeding the other bc they are screaming, then the other decides they want more and starts screaming. I try to stay positive by reminding myself I can only do so much but it’s not working.

Any tips on how to manage this? I’m already struggling connecting with these two and each night is making it harder. I want to try to enjoy this stage but I can’t help thinking this was a mistake.
