Logistics of feeding/burping/diapering both twins solo when taking shifts

We have three week old twins that are still waking up every 2-3 hours overnight, and the sleep deprivation is really starting to get to us. We tried each taking a shift a couple of nights ago and getting a longer stretch of sleep was amazing, but I found it so hard to manage feeding, burping, and diaper changes for two babies during my shift. Oh, and pumping.

So I would love to hear how you do it! No detail is too small.

Twin A is primarily nursed, while twin B primarily takes bottles of fortified breast milk. The other night when it was my shift I tried to nurse A and bottle feed B, which may have been part of the problem. I’d be open to bottle feeding both (which is what my husband did during his shift). We’re also eventually hoping to transition twin B over to primarily nursing - I can manage tandem nursing pretty well. But anyway, I would welcome logistics for any of the different ways we can feed twins!

Also, just want to mention that twin A is usually the one that wakes up every 2-3 hours. Twin B can usually go closer to 4 hours, but we have been trying to keep them on the same schedule, so we wake him up when twin A wakes. I think that’s the right move? But open to being told otherwise!
