How do I tandem breastfeed my 4.5 month old twins!?

I pump ~95% of my twins' meals and we only nurse occasionally at night in the side lying position. It's just easier to do bottles, as I'm their sole caregiver a majority of the time, and both boys like to stay latched for a very long time just comfort nursing. Which I would be fine with, but I have the other baby to worry about!

I've tried tandem feeding all of like 3 times since they've been born (using a twin Z + other various pillows) and I found it super awkward/uncomfortable. I always thought when they got older it might be easier.

Well, they got their 4 month vaccines yesterday and they are feeling just terrible. They both want to be held and so I have just been taking turns holding one while the other fusses or cries on the floor. 🙃 I thought, "you know what they might find super comforting? Nursing! At the same time!" Nah, it was a disaster. I cannot get into a comfortable position with them both in football hold and one of them inevitably ends up crammed into a position he hates and he starts screaming. Am I doomed if I don't have someone to help me get them positioned? I also have somewhat small breasts so I REALLY have to hunch over to get a boob in each mouth.

I had dreams of tandem breastfeeding my babies, I watched videos and did a bunch of reading when I was pregnant, I took so many breastfeeding classes... and here I am pumping and giving them bottles, which is fine, but I know right about now they need some extra comfort and it's just so agitating that I can't do that for them.

I guess I went on a tangent here but my point is, does anybody have any advice or insight on starting tandem feeding this late in the game?

Thanks in advance!
