Noticing a drop in supply

I eliminated my middle of the night pump ( I’m exclusively pumping) and I’m slowly but surely noticing my output going down. I went from overproducing to now barely making enough for him. I am enjoying the extra sleep (he’s also sleeping through the night finally) but I am not happy about my supply going down. Hubby will be out of town for two nights so I’d really like to wait until he’s back to reintroduce the middle of the night pump (so he can feed babe while I pump). Other than that I wonder if adding an extra pump during the day would have the same effect as adding the session at night? I’d love to continue sleeping more AND get my supply back lol

Help meeeeee, I’m poor (bridesmaids joke haha)
